Just discovered this new Sankey diagram video via e!Sankey Forum. Apparently just meant as a a show case for the possibilities offered by the e!Sankey software development kit (SDK).
We can see mass flows on a production line with two machines feeding ‘Item A’ and ‘Item B’ into the main production line.
These seem to be hourly flow values over a 30-hour time span. There are some red warnings indicating low buffer, and even one or two times when the production runs dry. Interesting…
Found that there are some more (educational) videos on youtube now that deal with Sankey diagrams.
