Contest entry - Romain Sacchi

[romainsacchi]

Submitter

My name is Romain Sacchi.
I am a postdoctoral researcher working with Life-Cycle Assessment at the Paul Scherrer Institute.

Description

I showcase here polyviz, a small library that allows generating graphs with the javascript library d3.js using data generated with brightway2.

This is a Python package that provides an interface between the brightway2 LCA framework and the D3.js JavaScript library. It is designed to be used in Jupyter notebooks, and provides interactive visualizations of LCA results.

This interface extends the capabilities of d3blocks, and makes it compatible with results generated by brightway2.

polyviz allows the following visualizations to be created from LCA results:

• Sankey diagrams (example 1, example 2)
• Chord diagrams (example 1, example 2)
• Force-directed graphs (example 1, example 2)
• Treemaps (example 1, example 2)
• Choropleth maps (example 1, example 2)
• Violin plots (example 1, example 2)

Database(s) used

• Used example data from the contest repository
• Used another database 👉 ecoinvent 3.8 cutoff
