Sankey diagrams are used to depict the flow of data between several categories. This chart type is very good at giving viewers a clear picture of how values transition and split from one set of categories to the other. If you are a Google Analytics user you have probably seen a version of Sankey diagram in their Behavior Flow, Goal Flow, and similar diagrams.
