Description

Visualize uncertainty of LCA graph data with sankey diagrams.

Sankey diagrams are next to bar charts one of the most famous ways to visualize LCA data. This can be explained with the very intuitive way to visualize the contribution of the supply chain. But the amount of information of sankey diagrams is limited. Inspired by a paper from Vosough et al, where different approaches to visualize uncertainty with sankey diagrams are researched, I implemented two different ways to visualize Monte Carlo graph results of brightway2 activities with the plotly sankey package.
For the graph traversal, an adjusted version of the bw2analyzer function "recursive_calculation_to_object()" from brightway2 is used.
It is tested with brightway2.5 and ecoinvent 3.8 cutoff.
