I like to create a sankey diagram with multiple destinations/layers/levels.
Example:
A parts was produced at location "a" (first destination), goes to shop at location "A" (second destination), to customer at location "alpha".
There are production sites "a" and "b", shop locations "A", "B" and "C" and serveral customer locations "alpha" ... "omega".
How can I realize suchh a digramm?
Thanks for assistance.
