New section on the SankeyMATIC site:
“Data: Interesting Diagrams from the Real World” at https://sankeymatic.com/data/

The first examples there show financial results for companies over time, with the first (of several) being Apple.

You may have already seen such diagrams presented elsewhere in Sankey form.

What's new here is:

1. Each diagram is overlaid on the *same* period’s results from the year before

2. There's a slider so you can compare them. (I'll post an animated example in a thread.)
