# easylayout: an R package for interactive force-directed layouts within RStudio <img src="https://github.com/user-attachments/assets/87ce78cf-53cc-4c07-8238-b138d62a4ca6" height="140" align="right" style="padding-left:10px;" />

easylayout is an R package that leverages interactive force simulations within
the IDE itself (e.g., RStudio, VSCode). It is **not** yet another visualization
library, but instead aims to interconnect existing libraries and streamline
their usage into the R ecosystem.
easylayout takes an igraph object and serializes it into a web application
integrated with the IDE's interface through a Shiny server. The web application
lays out the network by simulating attraction and repulsion forces. Simulation
parameters can be adjusted in real-time. An editing mode allows moving and
rotating nodes. The implementation aims for performance, so that even lower-end
devices are able to work with relatively large networks. Once the user finishes
tinkering the layout, it is sent back to the R session to be plotted through
popular libraries like ggplot2 or even the base package itself.
## Installation
You can install the development version of easylayout from [GitHub](https://github.com/) with:
```r
# install.packages("devtools")
devtools::install_github("dalmolingroup/easylayout")
```
## Example
This is a basic example which shows you how to solve a common problem:
```{r example, eval = FALSE}
library(easylayout)
library(igraph)
g <- igraph::erdos.renyi.game(n = 5000, p.or.m = 10000, type = "gnm")
number_of_vertices <- igraph::vcount(g)
igraph::V(g)$label <- NA
igraph::V(g)$size <- sample(1:5, number_of_vertices, replace = TRUE)
igraph::V(g)$color <- sample(rainbow(5), number_of_vertices, replace = TRUE)
plot(g, layout = easylayout, vertex.label = NA, margin = 0)
```
## Future work
The current implementation focuses on the R ecosystem, but using web
technologies makes it easily portable to similar environments, like Jupyter
Notebooks. We expect this tool to reduce the time spent tweaking network
layouts, allowing researches to generate more compelling figures.
