Sankey chart

A Sankey chart is a visualization that shows the directional flow of processes and activities from an initial node to a terminal point through interconnected lines. The width or thickness of the interconnecting lines is proportional to the flow rate. The width of each connecting line is determined by the value of the corresponding pairing, relative to other values present in the data.
