Sankey

One source bar whose height is the whole quantity, then a ribbon to every destination, each ribbon as thick as the amount it carries. The destinations must sum back to the source, which is why a Sankey almost always grows a node called unaccounted. That node is the finding more often than any of the named ones.

Example

Best when one pool splits into several destinations and you suspect the leftovers are large.
