i am waiting for someone to surpass the original steam engine sankey diagram: https://commons.wikimedia.org/wiki/File:JIE_Sankey_V5_Fig1.p...
the diagram is calculated with d3-sankey & rendered with imgui. you can stretch that window however you want—ok, enough.
edit: the original steam-engine sankey diagram created a far stronger emotional reaction in me. the aella chart is just more modern, i guess?
