Title : How people get around, by modal share %

Easiness:

• The % of mode of transport is shown in easy way.
• The legend is clearly mention. The color looks appropriate, like Walking or biking is environment friendly, hence in green.

Effectiveness:

Works well :

• If the purpose is to look for percentage of modal of get around at each part of the globe, this is partially effective. That is, many regions are covered.

Didn't work well :

• Many parts of World, like Africa & Australia are not shown here.
• Aggregate at continent level is not directly available.

Correctness:

What worked well:

• The length of bar looks like proportionate to the value.

Didn't work well :

• The total % at each region are not always 100%. For example, total for North America is 101% , total for Sothern Europe is 99%.
• It's not clear whether the meaning of car is only road-car or this includes chartered flight, cruse etc also.
• Though 'world average' is shown here, it's not clear whether this is the average of the figures shown here only or true world.

What could be better:

• The numbers should have been adjusted so that total would be 100 for each region.
• The meaning of 'world' should have been clarified.
• 'World Avg' should have been shown differently from other region. This could have been shown with different typeface, size or color or boxed.

Title: Hierarchy of Digital Distractions
Student: Prashant Sharma, BS in Data Science and Applications IITM, 21F1004586
Link: https://infobeautiful4.s3.amazonaws.com/2015/05/1276_hierarchy_of_digital_distractions.png

Critique

How effective is it at what it aims to do and what works well?

• Clear Hierarchical Structure:

1. Visual Pyramid: The pyramid shape effectively illustrates the concept of increasing distraction levels from bottom to top.
2. Distinct Sections: Each layer of the pyramid is clearly labeled, showing a gradation from less to more distracting activities.

• Effective Use of Color and Space:

1. Color Gradient: The gradient from light to dark blue provides a clear visual cue about the severity of distractions.
2. Whitespace Utilization: Adequate whitespace prevents the infographic from appearing cluttered, enhancing readability.

• Relatable and Engaging Content:

1. Use of humorous and relatable examples (e.g., “email linking to video of kittens frolicking”) makes the infographic engaging and memorable.
2. Descriptions like “email from romantic partner” or “Twitter RT’d by Twitterati” resonate with common digital experiences.

• Concise and Informative Text:

1. Minimal Text: Short descriptions avoid overwhelming the viewer and ensure quick comprehension.
2. Clear Labels: Each level of the pyramid has clear, concise labels that explain the type of distraction.

• Visual Appeal:

1. Simple Design: Simple, clean design makes the infographic aesthetically ok.
2. Icons and Symbols: Use of icons and symbols helps in quickly identifying different types of distractions.

What doesn’t work well?

• Overgeneralization / lack of credible support for hierarchy:

1. Overgeneralization of the impact of certain distractions (like – Facebook stranger (hot), stranger (known)), as individual experiences with distractions can vary widely.
2. Some categories might not accurately reflect the significance of certain distractions for all users.

• Subjective Ranking:

1. Personal Bias: The hierarchy is subjective and not based on empirical data, reflecting the designer’s personal view of distraction levels.
2. Variability: Different users might rank these distractions differently based on personal habits and preferences.

• Small Text and Readability Issues:

1. Some text of the pyramid is small and may be difficult to read, especially for viewers with visual impairments.
2. The mid-levels of the pyramid contain more text, making them appear cluttered compared to the upper levels.

• Device and Platform Focus:

1. The infographic focuses heavily on specific devices (e.g., iPhone) and platforms (e.g., Twitter, Skype), which might not encompass all potential digital distractions.
2. Other significant digital distractions (e.g., gaming, streaming services) are not addressed.

• Cultural and Demographic Bias:

1. The examples used may be more relevant to certain cultures or age groups, limiting the infographic’s applicability to a global audience.
2. Older generations might not find the examples as relevant as younger, more tech-savvy individuals.

Article Link : https://www.visualcapitalist.com/visualized-the-worlds-population-at-8-billion/
Image:

Short Critique
Effectiveness:

The visualization effectively communicates the distribution of the world's population by country. It provides a clear, quick understanding of how the global population is distributed geographically.

What Works Well:

Color Coding: The use of distinct colors for each continent makes it easy to differentiate between them also the use of different shade for the countries in the same continent aids in quick identification of each country.

Labels: The labels are clear and appropriately placed, aiding in quick identification of each continent.

Relative Size Representation: Showing regions with the most population as larger helps in quickly understanding the relative population densities of different areas.

Simplicity: The simplicity of the visualization can be a strength, making it easy for viewers to understand at a glance. However, it might also be a limitation if viewers require more detailed information about specific countries or regions.

Weaknesses:

Lack of Specificity: Not showing countries' original shapes can lead to ambiguity, as viewers may not be able to identify individual countries or regions accurately also Without the actual shapes of countries, viewers might misinterpret the data. For example, a large, sparsely populated country might appear smaller than a small, densely populated country, leading to incorrect assumptions about population density..

Distortion: The use of a globe can distort the perception of population distribution, especially for countries placed near the poles in the visual, which may appear larger than they are in reality.

Lack of Country Details: Viewers cannot see the shapes or boundaries of countries, which may be important for understanding geopolitical contexts or specific population distributions within countries.

Clarity and focus: Since distribution is based on countries the use of continent names for regions may lead to confusion (e.g rest of east Asia 36M). Consider using country names or alternative labels to maintain clarity.

Color coding: Color shades for the countries of a continent should have been selected based on the population of the country.

Suggestions for improvement:

Interactive Elements: Incorporating interactive features like tooltips or clickable regions to display detailed population information for each country.

Data Transparency: Providing access to the underlying data or methodology used for the visualization can enhance trust and understanding among viewers.

Scale Representation: Including a scale or legend to indicate how the globe's size and color correspond to population density can improve clarity.

Title: "The World Wide Web: A Breakdown of Internet Usage by Country"

Name: Kaustav Goswami
Roll: 21f1001588

Article Link: https://www.visualistan.com/2016/03/the-world-wide-web-a-breakdown-of-internet-usage-by-country.html

Strengths

1. Visual Appeal:

   • The circular format is visually engaging and makes the data more interesting to look at.
   • The use of colors to differentiate various metrics helps in quickly identifying patterns and trends.

2. Detailed Data:

   • The infographic covers 216 countries, providing a thorough analysis of global internet usage.
   • The breakdown of internet users by country and the percentage of each country's population using the internet offer valuable insights.

3. Multiple Metrics:

   • It includes various aspects of internet usage such as the total number of users, the percentage of the population online, the share of global internet users by country and the most popular browsers.
   • The heat map in the center showing internet penetration percentages adds depth to the data presentation.

4. Clear Labels and Legends:

   • Labels and legends are clear and provide enough context to understand the data without needing additional explanations.
   • The color-coding is intuitive, especially in the heat map, where warmer colors indicate higher internet penetration.

Weaknesses

1. Complexity:

   • The infographic is very dense and may be overwhelming for some viewers. The sheer amount of data presented can make it difficult to digest at a glance.
   • The circular format, while visually appealing, can be harder to read compared to a more straightforward bar or line chart, especially for precise values.

2. Color Usage:

   • Although colors help differentiate data, the palette used for the percentage breakdown around the circle can be confusing. Similar shades may not be easily distinguishable for some viewers.
   • The color scheme in the heat map could be problematic for colorblind individuals and there is no alternative provided for these viewers.

3. Browser Popularity Section:

   • The section on browser popularity is small and somewhat disconnected from the rest of the data. It might have been more effective if integrated into the main circular chart or given more prominence.
   • The data on browser popularity is minimal compared to the detailed country-by-country internet usage data, creating an imbalance.

4. Lack of Context:

   • The infographic does not provide information on the sources of its data, which is crucial for validating the information presented.
   • There is no time reference indicating when the data was collected, which is important for understanding the relevance and timeliness of the information.

5. Interactivity:

   • In a static format, the infographic lacks interactivity, which could have been beneficial for exploring specific data points more deeply. An interactive version would allow users to hover over sections to get detailed information.

Recommendations

1. Simplify the Design:

   • Simplifying the layout to make it more readable. Breaking it down into multiple smaller infographics or a more traditional format might help in understanding the data better.

2. Improve Accessibility:

   • Using a more diverse color palette and provide patterns or textures to help differentiate data points for colorblind users.
   • Adding a legend or a tool-tip style interactivity (if digital) would enhance accessibility.

3. Add Context and Sources:

   • Including the source of the data and the date when it was collected will add credibility and context to the infographic.
   • A brief explanation of key insights or trends observed in the data can help guide the viewer.

4. Enhance Browser Data Section:

   • Expand the section on browser usage or integrate it more effectively into the main chart. Providing more detailed insights or a separate infographic focused on browser trends could be useful.

Overall, I feel that this infographic is rich in data and visually compelling but simplifying its design, improving accessibility and providing more context would significantly enhance its effectiveness and user-friendliness.

Percentage of Americans That Identify As Christians - Fox News

Fox News broadcasted the following visualization which is semantically incorrect. Let's look at it in brief below

Source(0:22)

What's wrong

• From the graph, the change from 77% to 65% looks huge

Why it's wrong

• If you notice closely, the y-axis starts from 58 and not zero.

  • This sets a wrong perception while the actual statistics wouldn't have looked this bad
  • This created an unnecessary bias towards the inference from the viz.

• There is an inconsistency with mentioning the percentage of each bar representative.

  • One bar has the 77% inside while the other bar shows 65% just above the bar.
  • This kind of inconsistency should be avoided, as per design principles

What could have been right?

• I found the below image which extends the y-axis to start from zero
  
  source

• The difference between the two statistics is not huge and should have been conveyed correctly by starting the y-axis from 0.

• The other thing is to write the labels of each bar in a uniform manner: either both on top or both below

Things that are just correct

• I like the colors used in the graph.
  • The background is blue: dark
  • The bars are yellow: lighter than the bg
• They used a data viz principle to make the right usage of a dark-light color scheme

What they are trying to show:

The rising cost of training AI models over time.

What's working:

• The text written as annotation about the cost of training AI models is directly conveying the cost and keeping cost for all the years together is helping in comparision.
• Sequencing the spheres in a trail with years mentioned is able to give sense of chronology.

What's not working:

• Potraying models as spherical shapes. It is not clear that what parameter of the shape is mapped to the cost variable- diameter, area or volume. Also, if we consider the 3d effect, it is not clear that the size considers the distance, i.e, farther shaped will be smaller.
• What variable do the color of the spheres account for is not clear. It seems like it is randomly assigned.
• Creating a 3d view of the model spheres is creating confusion in which models are trained in which year especially in the years 2023 and 2024.

Title - CO2 Emissions by Country (2019)
Link - https://ourworldindata.org/grapher/annual-co2-emissions-per-country

Critique:

Effectiveness:
The visualization aims to present the annual CO2 emissions by country for the year 2019. It displays the emissions for each country, which is effective for comparing the values across different countries.

What Works Well:

• Color Coding: Different colors are used to distinguish between countries, enhancing visual differentiation.
• Labels: The chart includes labels for each country and the corresponding emission values, making it straightforward to interpret the data.
• Title and Axis Labels: The title clearly indicates what the chart represents, and the axis labels provide necessary context for understanding the values displayed.

What Doesn't Work:

• Overcrowding: With many countries represented, the chart can become crowded, making it difficult to discern smaller values and read all the labels clearly.
• Lack of Context: The chart does not provide contextual information such as population size or GDP, which can be important for understanding the relative impact of emissions.

What Could Be Better:

• Interactive Elements: Adding interactive features like tooltips, zoom, and filtering options could enhance the usability of the chart, allowing users to explore the data more deeply.
• Additional Context: Including data on population size or GDP alongside CO2 emissions could provide a more comprehensive view of the emissions' impact and fairness.

Overall, the bar chart effectively communicates the CO2 emissions by country, but some enhancements could improve its readability and provide a deeper understanding of the data.

Pros

• The picture depicts the information to be conveyed that is different types of data visualization tools. It contains different tools like Pie Chart, Venn Diagrams etc.
• Color encoding is attractive and grabs the attention of the viewer to the details.

Cons

• It's not beginner friendly. Say someone new with no idea of what data visualization or even chart looks like, they won't be able to recognize the name of the chart.
• Each tool is listed but not even a small detail about their use case has been specified in the picture.

CO2 Emission vs. Vulnerability to Climate Change by Nation Across the World

Aim of the given visualization

This visual presents a precise report of CO2 emissions and climate change vulnerability data of nations as of 2010. It aims to gently remind and warn nations to stop excessive CO2 emissions.

How effective is the given visualization?

At first glance, this visual stands out because it is clear and easily understandable. The title, visual, and color labels clearly convey the intended message without clutter, effectively covering the data of all nations.

Things that work well in this visual

• The data presentation is clear, precise, and straightforward, covering all aspects of the underlying message.
• The aesthetic is pleasing as the color composition is easy on the eyes.
• It effectively covers the entire data of emissions and climate change vulnerability, delivering a gentle reminder or warning about the consequences of excessive CO2 emissions.
• The labels help specify the issues and represent their extent.
• Despite the challenge of annotating data for every country, it effectively uses labels to extend issues in terms of size as the measurement.

Things that don’t work well in this visual

• The title is not eye-catching, which is crucial for any visual. It is written in dark and small text.
• The visual requires extra effort to zoom in to understand its content, which detracts from its effectiveness.
• The background color makes the visual somewhat dull and less eye-catching.

What could be better?

• A clear and bold title would be preferred over the current title.
• Increasing the size of the visual and the labels would improve readability, reducing the need to zoom in.
• Using a white background instead of a shady color would make the visual more eye-catching.
• The color composition could be adjusted to be more vibrant or bold to enhance the impact of the visualization.

Visualization Critique: Women's Wages - Jobs with the Highest and Lowest Pay Gaps

Critique

Effectiveness

The visualization aims to highlight the jobs in which women earn the most and the least compared to men, expressed as a percentage of men's earnings. It effectively demonstrates the disparity in earnings across different occupations, providing a clear comparison between jobs where women are relatively better paid and those where they face significant pay gaps.

What Works Well

• Clear Comparison: The use of a balanced scale to represent jobs with the highest and lowest pay gaps is visually intuitive and effectively conveys the disparity.
• Percentage Values: Displaying the exact percentage values next to each job category allows for an immediate understanding of the pay gap magnitude.
• Categorization: The separation of jobs into "Earn the Most" and "Earn the Least" categories simplifies the comparison and highlights the extremes in pay disparity.
• Design and Color Scheme: The color scheme is consistent and easy on the eyes, making the visualization visually appealing and easy to read.

What Doesn't Work

• Lack of Contextual Information: The visualization does not provide background information on why these disparities exist or how these percentages were calculated. This limits the viewer's understanding of the root causes of the pay gaps.
• Static Nature: As a static image, it lacks interactivity, which would allow users to explore more detailed information about each job category, such as average salaries or trends over time.
• No Geographic Context: The visualization does not specify if the data is specific to a particular country or region, which is crucial for understanding the context of the pay gaps.
• Limited Scope: Only showing the top five and bottom five jobs might oversimplify the issue and omit important information about other job categories with significant pay gaps.

Suggestions for Improvement

• Provide Context: Adding information about the factors contributing to these pay gaps and how the percentages were derived would provide a more comprehensive understanding.
• Geographical Specification: Indicating whether the data is global or specific to a particular country or region would help contextualize the information.
• Broader Scope: Including more job categories or a distribution of pay gaps across a wider range of occupations could provide a fuller picture of the issue.

Saranya Nayak
21f1005767

What works?

• Using different contrasting colors to categorize orbits, and sub-categorizing satellites by weight with varying shades of the same color, is an effective method for organizing and displaying data compactly and efficiently.

• Initially, I thought that choosing the origin at the top instead of the bottom for displaying “Satellites in Low Orbits Are Taking Over the Skies” conveyed the opposite meaning. However, I then realized our minds are trained to read from top to bottom. These clever positioning of the origin makes it an effective starting point for the graph.

• Incorporating arrows in the legends, rather than relying solely on numerical labels, provides clear visual cues and enhances the data’s interpretability. It’s a smart way to facilitate quick comprehension.

What doesn’t work/ what can be improved?

• Horizontal grid lines help in aiding data comparison for a specific year. Their absence makes it difficult to interpret the data accurately. Consider adding those grid lines to enhance clarity.

• The uneven pyramid structure can introduce ambiguity when interpreting the length and corresponding satellite count. Opting for a flat base would certainly enhance clarity and readability.

FINALM CONCLUSION:

OVERALL, THE STATIC VISUALIZATION EFFECTIVELY CONVEYS THE INCREASING NUMBER OF SATELLITES OVER TIME, ESPECIALLY IN THE LOWER ORBITS IN AN SIMPLE YEAT EFFECTIVE WAY.

2. This line diagram says regarding every player perfectly by specifying name close to each line. Through this Basketball fans can understand without any problem.

CONS:

1. An excessive number of lines in a diagram makes portrayal monstrous and unfit to appropriately snatch information.

2. As well as diagram determines current players in Blue variety color which doesn't exactly measure up for well with this setting as we can see players line of Stephen Curry and Rudy not ready to contrast information and different players.

3. Dim or blurred lines in diagram doesn't address well and an excessive number of lines are available and makes like dissipate outline each lines converge with one another . Any reader not ready to figure out information of past players.

Title - Big Mac Index: Price of a Big Mac in Different Countries
Critique:

Effectiveness:
The visualization effectively compares the cost of a Big Mac across different countries, providing insight into currency value and purchasing power parity.

What Works Well:
Clear Comparison: The bar chart format makes it easy to compare the prices of Big Macs across various countries at a glance.
Color Coding: Different colors for each country help to distinguish between them quickly.
Data Labeling: Including the actual prices on the bars enhances readability and immediate understanding.

What Doesn't Work:
Lack of Context: The visualization does not provide context on why the Big Mac Index is significant or how it relates to currency valuation.
Absence of Trend Information: It’s a static visualization and doesn’t show changes over time, missing the opportunity to illustrate trends in currency valuation.
Overcrowding: If there are too many countries, the chart can become cluttered, making it difficult to read and compare prices.

What Could Be Better:
Adding Annotations: Including brief annotations explaining the significance of the Big Mac Index and its implications for currency valuation would add depth.
Trend Line Addition: Incorporating a trend line or small multiples to show changes over time could provide more insights into how the purchasing power of different currencies evolves.
Interactive Elements: An interactive version where users can hover over bars to get more detailed information or filter by region could enhance engagement and usability.

Title: 2024 Lok Sabha Election Poll Results by Parties in various constituencies

Source Image: https://upload.wikimedia.org/wikipedia/commons/d/d2/Indian_General_Election_2024.svg

Cons :

1. The map size could be more prominent and easier to navigate.
2. The constituencies are not named on the map; hence, it is difficult for someone without location knowledge to know which constituencies are being shown.
3. There needs to be a clear indication of what the numbers represent, and there is no mention of its use anywhere in the article.
4. Some smaller constituencies are not shown in the map and, hence, are zoomed in to make it relevant.
5. Not all the parties are shown on the map; only the major parties of the two major alliances are highlighted. The other parties are clubbed together as one.
6. The colour coding for various parties has the same colour grading; hence, it is difficult to differentiate one party from the other.
7. The visualization is in the shape of a map of India, but the amount of data cramped into this small space is more than required.

Things to Improve :

1. The map can be annotated to give an idea of what the various data points in the map represent.
2. The representation of constituencies and their winning parties can be represented as a simple table as it is much more easily interpretable.
3. The parties can be given colors that are not on the same gradients.

Title - Infographic on Infographic!
Link - https://cdn.mos.cms.futurecdn.net/XXxLwkoq9okWaN2iLn8sX7.jpg

Critique

Objective

The visualization aims to present essential purpose of an infographic. As the author says, "An infographic is a picture that blends data with design, storytelling, and insights that helps nonprofits concisely communicate messages to their audiences." The creative presentation in this infographic looks to bring out the difference between data, information, presentation, and visualization.

What Works Well

Almost everything seems to work well in the visualization. A few specific items are:

• The progression from data to visualization clearly delineates the steps in data visualization
• Brilliant choice of lego blocks to represent data items - these are colourful and intuitively give the cue of 'organizing'
• The title frame is well designed and actuall shows samples of many visualization
• The design minimizes the amount of text, legends, etc. - The pictures practically speak for themselves
• The background is white and accentuates the colours of the lego blocks
• Each subitem (which are actually photographs) shares equal space

What Doesn't Work

Most of the elements of the visualization fit together and there are very few 'mistakes'.

• The title could have been desgined better to provide attention to the background pictures
• The footer provides credits to the photographer; however the logo of 'Hot Butter Studio' does not come out well

What Could Be Better

It is quite difficult to improve a product that is already very good. Since lego blocks are often used to create shapes, the last tile could have actually used shapes rather than simple arrnagement of the bricks. The other tiles have an element of 3-dimensions and the last title could have enhanced this further by making the shapes 'interact' with each other.

Title: Ranked: The 10 Most Visited Countries in 2023
Source: https://www.visualcapitalist.com/ranked-the-most-visited-countries-in-2023/

Objective: This visualization aims to depict the 10 most visited countries in 2023, based on the total number of foreigners entering each country.

Pros:

• Each country in the top 10 is ranked clearly and labelled with the number of tourists, fulfilling the main objective of this graphic.
• This visualization uses the world map as the background, which gives a fair geographical context.
• The use of well-designed icons for each country helps in quickly associating the country with its famous landmarks.
• The graph is visually appealing with its calm and pleasing blue colour scheme.

Cons:

• The list is not ordered, making it harder to find the rankings quickly.
• There is no mention of any scale in the map.
• This graphic could use a sorted bar chart not only to show the ordering, but also to provide a better perspective of ratios and differences between the number of tourists among different countries.
• The countries in the world map do not have borders. The perspective of the world map is also tilted, which makes it harder get accurate geographical perspective.
• The large tourist spot icons may have been over-stepping into the areas of neighbouring countries, which further messes up the geographical context.
• The colour scheme is aesthetically pleasing but the low contrast could be problematic for colour-blind viewers.

What could be improved:

While this visualization effectively fulfills its objective, there are places where it could be improved to make it more effective and accessible.

• Providing a small sorted bar chart using the number of tourists for the ranked countries.
• Drawing borders for the countries, at least for the ranked ones to provide a better geographical representation.
• Using smaller icons for tourist spots, or changing the place where they're displayed to avoid inaccurate depictions.
• Changing the perspective of the world map to the one which everyone is used to.
• Increasing the contrast between the colours to make the visualization more accessible and inclusive.

Title – Teenage Pregnancies
Source - https://jacksoninfographics.wordpress.com/wp-content/uploads/2015/04/1298303310teenage-preg-rate.gif

Objective: This visualization aims capture the reduction of the number of teenage pregnancies rate
from 1974-1983 in Toronto, Canada.

Pros:
• The visual is eye catching with its calm color scheme and design.
• Incorporating the teenage woman in the visual can convey the infographic’s story effortlessly.

Cons:
• Using per 1000 as the base doesn’t provide context on the total number of teenagers who are pregnant.
• There needs to be clarity for the legends. The blue and pink woman figures on the right used as legends are not easily grasped in the first go.
• Both the blue and pink line have been decreasing over the years. Does that mean the percentage of girl teenagers has reduced as well which could be the reason for teenage pregnancy have rate going down. Clarity on this would be useful.

What could be improved:
• Use of better legends, for easy differentiation between the lines.
• Comparison between the absolute number of girl teenagers and those who are pregnant in Toronto would be more useful and easier to understand.

Title: The Rise and Rise of A.I. Large Language Models (LLMs) & their associated bots like ChatGPT

URL: The Rise and Rise of A.I. Large Language Models (LLMs) & their associated bots like ChatGPT

Effectiveness

The visualization aims to depict the evolution and diversity of large language models (LLMs) over time, highlighting their sizes (in terms of parameters) and categorizing them by the organizations that developed them. It successfully showcases the rapid growth and variety of LLMs from different companies and research institutions, providing a clear historical context and current landscape.

What Works Well

• Clarity in Representation: The use of bubbles to represent different LLMs is effective, with bubble size correlating to the number of parameters, making it easy to compare models at a glance.
• Color Coding: Different colors represent different organizations, which helps in quickly identifying the major contributors to LLM development.
• Timeline: The x-axis provides a clear timeline from pre-2020 to 2024, showing the progression and emergence of various models over time.
• Annotations: Labels for well-known models and the inclusion of significant milestones (e.g., ChatGPT, GPT-4) provide context and make the graphic more informative.
• Open-Access Indication: The use of a distinct symbol (open circles) to denote open-access models is a useful addition for those specifically interested in accessible LLMs.

What Could Be Better

• Overlapping Bubbles: In areas with high density (e.g., between 2022 and 2023), bubbles overlap significantly, making it hard to distinguish between individual models. Adjusting the spacing or using a different layout might help.
• Detailed Information: While the visualization provides a high-level overview, it lacks detailed information on each model, such as specific capabilities or unique features. Including brief tooltips or a supplementary legend could enhance understanding.
• Scaling Issues: The scaling of the y-axis (billion parameters) could be more granular, especially for models with fewer parameters, to better highlight differences among smaller models.
• Model Placement: Some models are placed ambiguously on the timeline, possibly due to unclear release dates. Ensuring precise placement based on release or major update dates would improve accuracy.
• Additional Metrics: Incorporating other metrics such as training data size, compute resources used, or real-world application impact could provide a more comprehensive view of each model's significance.

Conclusion

Overall, the visualization is effective in communicating the rapid development and diversity of LLMs. Enhancements in handling overlapping bubbles, providing more detailed information, and refining the scale could make it even more informative and user-friendly.

The Spiraling Opioid Epidemic in America

The infographic titled "The Spiraling Opioid Epidemic in America" is effective in visually representing the dramatic rise in opioid overdose deaths over the last 20 years in the United States. It effectively highlights the three waves of the opioid crisis, providing a clear and impactful visual narrative.

What Works Well

• Color Coding: The use of distinct colors for pharmaceutical opioids, heroin, and synthetic opioids helps in differentiating the types of opioids contributing to the crisis.

• Wave Identification: The identification of three distinct waves (pharmaceutical opioids, heroin, and synthetic opioids) helps in understanding the evolution of the epidemic.

• Relative Potency and Lethal Dose Comparison: Including a comparison of the potency of different opioids and their lethal doses adds valuable context to the severity of the crisis.

• Global Comparison: The comparison of drug-related mortality rates across countries emphasizes the scale of the crisis in the U.S. compared to other nations.

What Doesn't Work and Can Be Improved

• Disproportionate Representation: The rose diagram makes the number of people dying from synthetic opioid overdoses look disproportionately larger compared to those dying from pharmaceutical opioid overdoses. This distortion occurs because the rose diagram uses areas to represent data, and humans are more sensitive to differences in length than area. The larger outer segments can exaggerate the perceived increase in deaths. A linear time series chart would be more straightforward and less prone to misinterpretation.

• Data Density: The infographic packs a lot of information into one visual, which can be overwhelming. Breaking it into smaller, more focused sections might improve clarity.

• Detailed Labels and Legends: Some labels and legends could be more detailed. For instance, the legend explaining the different opioid types could be more explicit about the years or specific substances involved.

• Text Size and Clarity: Some of the text, especially the smaller numbers and labels around the rose diagram, can be hard to read. Increasing the font size or simplifying the information could help.

• Interactive Elements: Consider creating an interactive version of the infographic where users can hover over or click on sections to get more detailed information.

Title: Learning Out of Poverty

Strengths:

• Visual Appeal: The infographic uses vibrant colors and engaging illustrations, which capture attention and make the data more relatable and memorable.
• Clarity and Organization: The content is well-organized, with each statistic clearly labeled and spaced out, ensuring viewers can easily follow the narrative.
• Humanization of Data: Each statistic is accompanied by a visual representation, such as images of children and mothers, which helps humanize the numbers and convey the message more effectively.
• Compelling Statistics: The infographic highlights critical benefits of education, including increased child survival rates, higher productivity, and reduced risk of HIV/AIDS.

Areas for Improvement:

• Color Contrast: While the colors are visually striking, the contrast between the text and background in some sections can make the text difficult to read. Enhancing this contrast would improve readability.
• Data Sources: The infographic lacks references to data sources, which are essential for credibility. Including a small footnote or link to the sources would enhance its reliability and trustworthiness.

Conclusion:

"Learning Out of Poverty" is a compelling and visually engaging infographic that effectively communicates the multifaceted benefits of education. By improving text readability and providing data sources, its impact could be further amplified, making it an even more powerful tool for advocacy and education.

URL: https://wccftech.com/amd-commands-30-of-cpu-market-share-for-1st-time-in-12-years-according-to-latest-cpubenchmark-data/

The stacked bar chart aims to visually represent the relative market share of AMD and Intel CPUs during Q3 2019.

What works well:

1. The use of contrasting colors (red and blue) makes it easy to distinguish between AMD and Intel's shares.
2. The precise percentage values are displayed for each segment, allowing viewers to quickly grasp the exact market share figures.
3. The simple and clean design with a clear title and legend makes the chart easy to understand at a glance.

What doesn't work well:

1. The lack of historical data or a time-series view limits the chart's ability to convey trends or changes in market share over time.
2. There is no additional context or explanatory text, making it rely solely on the surrounding information to explain its significance.

What could be better:

1. Including additional bars for previous quarters or years could provide more context and showcase the progression of AMD's market share gains over time.
2. Considering alternative chart types, such as a line graph or an area chart, could potentially convey the historical trend more effectively than a single stacked bar.
3. Incorporating additional data or dimensions, such as market share by product segment (e.g., desktop, server, etc.) or geographical region, could provide more granular insights.

This Visualisation shows the biggest acquisitions that happened in the tech world during 2020- The year the COVID-19 Pandemic hit globally

Strengths

• Visually Appealing: The contrast between the visualizations and background is clear helping the visualizations to stand out.
• Clear Timeline Structure: Since the data is temporal, having the data presented in a clear timeline format with the spacing reflective of real-time helps visualize the temporal aspect of the data.
• Having Logos: The logos of the companies involved being present give a better visual indicator and serve an easier data-driven storytelling aspect to the visuals.
• Clear Description of Labels and Important Information: The clear idea behind the labels is mentioned providing clarity to the labels. Also, the important aspects of the data are separately mentioned by words with clear association with the visual.
• Clear Citations: Clear Citations on the artist, the data source, and other people and organizations involved are visible.

Improvements

• Cluttering in Labels: Cluttering of labels is present, especially concerning the smaller acquisitions mentioned.
• Presence of White Space: There seems to be a lot of empty space in the visualization, it could have been more effectively used.
• Same color for labels and visuals: While it is aesthetically pleasing to have fewer colors in the visualization, the labels and visuals being the same color, especially in the more cluttered, and smaller acquisitions makes reading the labels more difficult.
• Lack of clear indication in visuals: The visualization doesn't clearly describe if the number of acquisitions maps to the size of the circle associated, the height, or both.

Conclusion

While the current design for the visualization is visually appealing and eye-catching, a simpler visualization could have been much more effective at conveying the information without much clutter or empty space.

Top Lithium Producers in 2023

https://www.visualcapitalist.com/ranked-the-worlds-largest-lithium-producers-in-2023/

Student: Kruttika Milind Soni (21f1001029)

Strengths

1. The use of the lithium mine visual to represent the data is very meaningful. It lends semantic encoding to the visualisation.
2. The colour and setting of the mine transports the viewer to the basics of what the data is about.
3. It specifies the unit and provides country names and flags to try to be more visual.
4. They have given the source of their data in the visualisation itself and also clarified that the numbers are estimates.

Faults and improvements

1. The slight perspective caused by viewing the data from a bird's eye view skews the perception of area. This creates a Ponzo illusion where we think the data in the background should be larger than it is.
2. Trying for realism has led to fuzzy edges which undermines the clarity that smooth edges provide.
3. The edges also have a depth being represented as pools of chemicals which also leads to confusion in the true size of the polygons.
4. The perspective unnecessarily leads to a 3D visualisation where a 2D visualisation was possible.
5. Use of percentage would have been a useful metric here.

It Fell From the Sky

Source: https://www.behance.net/gallery/95352539/It-Fell-from-the-Sky

This visualisation by Luiz Amorim depicts information about meteorite impacts. It uses a combination of elements like a world map, timeline, and text descriptions to showcase this data.

What works

1. Compelling title and image: The title “It Fell from the Sky” and the image of a meteorite immediately capture the viewer’s attention and effectively introduce the topic of meteorite impacts.
2. Use of color: The visualization uses a cool blue color scheme for the background and text, which is appropriate for scientific data visualizations and makes the bright orange highlights of the meteorites stand out.
3. Clear hierarchy of information: The visualization uses a clear hierarchy of information, with the title and subtitle at the top, followed by the main content area which includes a timeline, a world map and text descriptions.

What doesn't work

1. Lack of Precision: While the map shows impacted regions, it doesn't pinpoint the exact locations.
2. Misleading Bubbles: The size of the bubbles and their comparison based on weight might inaccurately portray the actual affected area.
3. Uneven Timeline: The timeline lacks years or even spacing between markers, making it confusing to interpret the data's temporal aspect.
4. Limited Connection: It's difficult to correlate impacted areas with specific time periods in the timeline.

What could be better

1. Timeline: An evenly spaced timeline and color coded timeline bars to visually represent the number of impacts per year.
2. World Map: Use different-sized symbols to represent the actual size of the meteorites, not their weight.
3. Text Descriptions: Condense the text to highlight key takeaways from the data.

URL: https://www.visualcapitalist.com/top-50-most-visited-websites/

Effectiveness:

The visualization effectively communicates the dominance and relative traffic volumes of the world's top 50 websites. It uses a circular layout with bubble sizes proportional to the amount of traffic each site receives, making it visually impactful and easy to grasp the overall landscape of internet usage.

What Works Well:

1. Visual Hierarchy: The use of circle sizes proportional to traffic volume is intuitive, allowing users to quickly see which websites are the largest in terms of traffic.
2. Colour Coding: Different colours represent different categories of websites, making it easy to distinguish between various types of online services (e.g., social media, news, search engines).
3. Concise Information: Each circle includes the website name, URL, country of origin, and traffic volume in a compact format, providing all necessary information at a glance.
4. Additional Insights: The inclusion of additional insights, such as the total traffic for top websites and high-duration visits, provides more context and adds value to the visualization.

What Doesn't Work:

1. Visual Overload: The circular layout with numerous overlapping circles can feel cluttered, making it challenging to focus on individual elements. This can overwhelm viewers and reduce the effectiveness of the information being conveyed.
2. Overlap in Categories: Some websites might belong to multiple categories (e.g., Facebook as both a Social Media Network and a Streaming & Online TV service), but the visualization does not account for these overlaps, which can lead to confusion.
3. Font Size and Style: The small font size used for labels, especially in smaller circles, is difficult to read. Additionally, the font style may not be the most legible, further impacting readability.
4. Disproportionate Emphasis: The largest circles (e.g., Google) dominate the visual field, potentially skewing the viewer's perception and overshadowing other relevant sites that might also be influential in their respective domains.

What Could Be Better:

1. Simplified Design for Smaller Websites: Reducing the number of websites shown or grouping lower-traffic sites into categories could help alleviate the overcrowding issue.
2. Enhanced Contrast: Using a more distinct colour palette with higher contrast between categories would make it easier to differentiate at a glance, especially for users with visual impairments.
3. Multi-Category Indication: Implement a system to indicate websites that fall into multiple categories. For example, use pattern fills or multi-coloured borders to represent multiple categories.

Conclusion:

Overall, this visualization is effective in showcasing the dominance of the top 50 websites, but it could be improved with better handling of small-scale data, and an optimized colour scheme for better readability and accessibility.

Global Hunger Index in 2018

Aim and Effectiveness

The map aims to show world hunger levels by country in 2018. It uses color coding to represent different levels of hunger severity, ranging from “very low” (in green) to “extremely alarming” (in dark red). This is a fairly effective way to communicate the information, as color coding is a well-recognized way to represent data.

Strengths

1. Easy to understand: The color coding system is easy to understand, even for people who are not familiar with the Global Hunger Index.
2. Clear legend: The legend clearly defines the different color categories and their corresponding hunger severity levels.

Weaknesses

1. Limited data visualization: A choropleth map, like this one, only shows one data point per region. It can be difficult to see the variations in hunger levels within a country, especially for larger countries.
2. No scale: The legend provides the definition of the categories, but it does not show the numerical scale used to determine which category a country falls into.

Improvements

1. Include a scale on the legend: Adding a scale to the legend would allow viewers to see the exact hunger score for each color category.
2. Consider using multiple data points per country: If data is available, it could be useful to show hunger levels for different regions within a country. This could be done using different colors or shadings within each country boundary.

Conclusion

Overall, the map is a reasonably effective way to show global hunger levels at a glance. However, it could be improved by including more data visualization techniques.

Introduction:

The Median age is a single indicator of the age distribution of a population- where half the population is older and half is younger than the listed age. It can help government and private companies plan for age-specific demand for goods and services from the resident population. World median age is 31 years and India's age is 30 years.

What Works:

• The Top 10 Oldest & Youngest countries are provided separately, which good and it can be easily observed.
• Definition of Median Age is included in the infographic, which enhances the readability among the viewers.
• Location of the country and its age is mapped as circle in the respective region to understand the region the belong in the world level
• Colour coding of bubbles effectively to highlight the Green for the younger age’s countries below the median age of the world and red for the countries with Older ages as their median.
• Credits source for the details provided clearly at the end, that enables the viewers to do fact check if required.

What Doesn’t work and can be improved on:

• Not all countries information available in the infographic, only the top 10 younger and top 10 oldest are available along with worlds median. Other important region from most of the main continents are missing.
• Position and size of bubbles are not accurate to the size of the country in the world map. Its big and it’s out of scale which can mislead to viewers.
• Countries Maps are missing, if it provided, it would have been helpful for viewers to identify it quickly.
• Overlapping of bubbles are hard to distinguish.

Effectiveness

The visualisation depicts the relationship between cell phone service providers in NewZealand as to which company the consumer switches to while buying a new phone. It was done by data visualisation designer Nadieh Bremer based on Deloitte Survey Data.

What Works Well

• The Chord Diagram is a very intriguing and eye-catching way to visualise a Data.
• The Colours used for the the companies are perfect as those colours are the ones that strike our mind when we hear the names. For example : Grey for Apple, Dark Blue for Samsung, Green for HTC and so on.
• The mountains (hill-like chords) that represent the loyal consumers who stuck to the same brand while buying a new phone in each brand is an added detail.
• A single chord between two service providers give details about the consumers who switched between company A to company B and vice versa.

What Doesn't Work Or Could Be Better

• Individual Chords can be seen only when we hover over particular brands and it is difficult to interpret when all the chords are displayed at once.
• Further Visualisation of brands in the other category could allow us to explore further consumer behavioural pattern.
• Even though the brands are visualised according to their share in the market, the 15% of the consumers that are loyal to Nokia which has 20% market share looks the same size as the 18% of the consumers that are loyal to Samsung which has 42% market share.

Conclusion

This is one of the most Efficient and Effective Visualisations as it is almost perfect and communicates the phone behaviour pattern of the dutch people.It is very user-friendly and intuitive It was rightfully chosen for the shortlist of the Data Journalism category in the 2015 Kantar Information is Beautiful Awards.

50 Years of Video Game Industry Revenues, by Platform

Infographic Link: https://www.visualcapitalist.com/video-game-industry-revenues-by-platform/

Brief:
This visualization of video game industry revenues by platform offers a detailed look at how different market segments perform against each other. The various Industries categorized are Console, Mobile, PC, AR/VR, Handheld, and Arcade Gaming. These insights highlight the shifting dynamics in the video game industry over 50 years.

How effective is it at what it aims to do?
The graph aims to show the evolution of video game industry revenues across different platforms (arcade, console, PC, handheld, mobile, VR/AR) from 1970 to 2022, while also marking significant events and game releases that influenced the industry. It effectively communicates both the quantitative data (revenue growth) and qualitative data (industry milestones).

What works well?

1. Choice of Graph: The graph presented is a stacked area chart combined with a timeline. This type of visualization is effective for showing how different segments contribute to the total over time, as well as highlighting key historical milestones and events in the video game industry.
2. Data Labels: Each segment is labeled with the category and revenue figures, providing immediate context without the need for additional interpretation.
3. Historical Context: The inclusion of key milestones, game releases, and technological advancements (e.g., the launch of Atari 2600, iPhone, and Steam) adds valuable context to the data. This helps viewers understand the factors driving changes in revenue.
4. Visual Appeal: The use of retro gaming imagery and a vibrant color palette makes the chart visually engaging. This can help draw in viewers and keep them interested in the data.

What doesn't work well?

1. Overcrowding of Information:

   • Cluttered Timeline: The graph attempts to cover a large amount of historical data and significant events, which can make it look cluttered. The numerous milestones and annotations can overwhelm viewers, making it harder to focus on the revenue trends.
   • Small Text: Some annotations and text elements are small and may be difficult to read, especially for viewers with vision impairments or those viewing the graphic on smaller screens.

2. Complexity for Casual Viewers:

   • Visual Complexity: The stacked area chart combined with a dense timeline can be visually complex. Casual viewers or those unfamiliar with the industry might find it challenging to understand the detailed information quickly.
   • Layering Effects: The overlapping areas for different platforms might be confusing, particularly in sections where revenue contributions are similar in size. This can make it hard to differentiate the exact contributions of each segment at a glance.

3. Lack of Detailed Revenue Data:

   • Absence of Specific Figures: While the graph provides a general sense of revenue trends, it does not include specific annual revenue figures for each segment. Detailed numbers would provide a clearer understanding of the scale and growth of each platform.
   • Revenue Scale: The vertical axis shows total revenue, but it might be beneficial to have additional markers or lines to indicate significant revenue milestones (e.g., $50B, $100B) more clearly.

What could be better?

1. Detailed Data Labels: Adding specific revenue figures or growth percentages at key points in the graph could enhance understanding. While the overall trend is clear, precise data points would provide more detailed insights.

2. Breakdown by Region: Including regional breakdowns could add another layer of depth, showing how different markets have contributed to overall revenue trends.

Projected 2023 global GDP

Aim of the Visualization:

The primary goal of this visualization is to represent the projected 2023 global GDP (Gross Domestic Product) by visualizing the relative sizes of different economies. Using a circular chart, it aims to provide an overview of economic power distribution among countries and facilitate comparisons.

Effectiveness and What Works Well:

1. Concise Overview: The visualization effectively condenses a vast amount of economic data into a single image. Viewers can quickly grasp the relative importance of various countries without needing to analyze extensive tables or reports.
2. Visual Comparison: The circular format allows for easy visual comparison. Countries are represented as slices, making it straightforward to identify major players (e.g., China, the USA) and their approximate contributions.
3. Annotations: The inclusion of annotations adds context and highlights significant events. For instance, the annotation "India dethrones..." draws attention to India's rising economic position.
4. Memorability: The circular layout and labeled slices enhance memorability. Viewers are more likely to remember key points about global GDP distribution.

Areas for Improvement:

1. Color Choices: While color coding helps differentiate countries, the shades used are too similar. Using more distinct colors would improve readability.
2. Visibility of Minor Contributors: Although the visualization includes all contributing countries, those with smaller GDPs are difficult to read due to small font sizes and narrow slices. Larger or clearer labeling for these countries would help.
3. Proportional Representation: Ensure that the slice sizes are proportional to actual GDP values. Inconsistent sizing can mislead viewers about the relative economic sizes.
4. Abbreviation Clarity: Avoid using abbreviations that may be unfamiliar to the audience. Full country names or widely recognized abbreviations would be more effective.
5. Legend and Scale: Including a legend or scale to explain how circle sizes relate to GDP values would enhance understanding and accuracy.
6. Misleading Representation: Pie charts imply a whole that sums to 100%. For projected values, a different type of chart (e.g., a bar chart) might more accurately represent the data without implying a misleading completeness.
7. Additional Context: While annotations provide some context, more detailed explanations would improve comprehension. For instance, explaining why India's GDP position has changed adds valuable context.

Overall scope for improvement:

Refinements in color choices, label placement, and clarity would enhance effectiveness, While including more detailed contextual information and ensuring proportional representation would make the visualization more informative and accurate.

Party Wise Results Status: A table showing the number of seats won, leading, and the total number of seats for each party.
Effectiveness:
The dashboard aims to provide a comprehensive overview of the election results, including seat distribution, vote share, and detailed results status for each party. It effectively communicates key data points in a visually engaging manner, making it easy for viewers to understand the election outcomes at a glance.

What Works Well:
Visualization Choices:

Circular Graph for Seat Distribution: This type of graph is effective in showing the proportional representation of seats won by each party, giving a clear snapshot of the overall election outcome.
Pie Chart for Vote Share: It visually represents the vote share distribution among various parties, making it easy to compare their relative popularity.
Data Labels:

Each segment in the vote share pie chart is labeled with the party and percentage of votes, providing immediate context without the need for additional interpretation.
Results Status Table:

The table format clearly shows the number of seats won, leading, and the total for each party. This detailed breakdown helps in understanding the exact performance of each party in the election.
What Doesn't Work Well:
Cluttered Visualization:

Circular Graph Overcrowding: The circular graph showing seat distribution can become cluttered when representing a large number of parties, making it difficult to distinguish between smaller segments.
Pie Chart Overcrowding: Similar to the circular graph, the pie chart can become overcrowded with many small segments, making it hard to read and compare.
Lack of Detailed Data:

Specific Seat Numbers: The circular graph does not display specific seat numbers for each segment, which could provide more detailed insights.
Absence of Regional Breakdown: The dashboard lacks a regional breakdown of the results, which could provide additional insights into the geographic distribution of party support.
Visual Complexity:

Text and Annotations: Some text and annotations in the visualizations might be small and difficult to read, especially for viewers with vision impairments or those viewing the dashboard on smaller screens.
Color Distinction: The use of similar colors for different parties can make it hard to distinguish between them, especially in the crowded sections of the graphs.

Top 10 Largest Nuclear Explosions

Name: Arshpreet Kaur Dhanjal
Roll number: 21f1000788

Image source

The visualization aims to depict the ten largest nuclear explosions in history, focusing on the height of the explosion's "mushroom cloud," the yield in kilotons (kt) of TNT, the date and location of the tests, and the countries responsible. The graphic succeeds in providing a clear and impactful representation of this information, enabling viewers to understand the scale and historical context of these nuclear events.

What works well?

1. Visual Clarity: The use of mushroom cloud graphics for each explosion is effective and immediately communicates the subject matter covering both aspects (height and radius) of an explosion. The radius of the impacted area depicted within the graph gives additional information in a non-cluttered manner. The varying heights and detailed depictions of the clouds illustrate the relative size of each explosion.
2. Proper Key: The definition of a proper key giving detailed explanation about how to read the graph in a compact manner is a great addition to the visualisation.
3. Scale Comparison: Adding the illustration of Mount Everest and reference to Stratosphere is a clever addition to give relevant context regarding the height of the explosion.
4. Chronological Order: The visualisation effectively communicates the time progressive nature of the explosion giving the viewers insights on the evolution of nuclear explosions over time.
5. Utilisation of space for extra information: Additional information in the blank spaces help give viewers more detailed context and increases the information passed to the viewers in an efficient manner.

What doesn't works well and Potential Improvements.

1. Small Font Size: Text readability is reduced due to the relatively smaller font size in comparison to the visuals. Some of the text, particularly the annotations, is small and hard to read. This can be a barrier for viewers, especially those with visual impairments. Since there is a lot of free space, the font could have been increased for better readability.
2. Coverage of Available Area: The centre part of the illustration seems empty in comparison to the rest of the visual and more detail could have been incorporated there.
3. Bar Height Disparity: Difference in height in the upper layer and lower layer of the graphs is something that should have been avoided and can introduce some bias in the viewer's mind.
4. Colour Scheme: Though the colour scheme is apt for the context, it has made the visual a bit bland and could be improved by using contrasting range of colours to depict the information.

Conclusion

The visualization effectively communicates the scale and historical context of the ten largest nuclear explosions through clear and impactful graphics. The use of mushroom cloud imagery, chronological ordering, and scale comparisons with Mount Everest and the stratosphere add significant value. However, improvements can be made in text readability, utilization of empty space, consistency in bar height proportions, and the color scheme. Addressing these areas would enhance the clarity and overall effectiveness of the visualization, making it more accessible and informative for a broader audience.

Apple’s iPhone 2013 event featured a few very impressive-looking charts such as the dramatic increase in processor and graphics performance between the very first iPhone in 2007 and the iPhone 5s, but a far more controversial chart displayed “cumulative iPhone sales” since 2007 shown above.

My Analysis

• The chart omitted any y-axis scale, making the data unclear.
• The curve would naturally increase over time in a cumulative sales analysis, potentially misleading the viewer.
• iPhone sales have declined over the last three quarters, which is not apparent from the chart.
• Many cumulative sales went to existing customers upgrading or replacing devices.
• The chart doesn’t account for millions of units no longer in service.

A Few Recommendations

• Include a clear y-axis scale to provide context and transparency.
• Use a different type of chart that accurately reflects sales trends, such as quarterly or yearly sales figures instead of cumulative sales.
• Apple could have simply highlighted the "400 million" sales figure without using a misleading chart.
• Highlight both the total sales figure and the recent sales trends to provide a complete picture.
• Address the distinction between new customers and repeat customers to clarify the nature of the sales data.
• Incorporate information about the number of active devices to give a better sense of the current user base.

Drivers of Change: The reasons behind the significant increases or decreases in brand value are not provided, leaving viewers without context for these changes.

Comparative Growth: How these brands compare to the rest of the top 100 or other significant brands not in the top 10 is not visible, limiting a broader understanding of the market landscape.

Ways to improve
Adding context for growth drivers, comparative insights, and sector influence are areas where the visualization could be improved for a clearer understanding.
