More details available in the Readme and in the supporting presentation.

Database(s) used

• [X] Used another database 👉 ecoinvent
• [ ] Used example data from the contest repository

Note: any brightway2 LCA project may be used (and more generally, any graph data); the code and its visualisations are not specific to the ecoinvent database.

Links to the code and visualization

The overall project repository is https://github.com/SLU-biochar/bw2-widgets

Code

The code that generated the example submitted is in this notebook: https://github.com/SLU-biochar/bw2-widgets/blob/main/demo4contest.ipynb

Visualizations

The output visualizations are located in the folder html_export. The files are:

• page_waterfall_demo4contest.html (HTML file to open in a browser)
• widget_waterfall_demo4contest.js (JavaScript file containing the model data, and loaded by the HTML file)
• widget_plot_types.js (JavaScript file containing the plotting functions, and loaded by the HTML file)

To make use of the visualisation, download the 3 files in the same folder and open the HTML file. Something similar to the screencast below should appear in your browser:

Note: the numerical data in the file widget_waterfall_demo4contest.js was replaced by dummy data to comply with the end-user license agreement of the ecoinvent database.
