What is a Sankey Diagram?
Sankey diagrams display flows and their quantities in proportion to one another. The width of the lines indicates the amount of flow so the thicker the line, the larger the quantity of flow.
Flow lines can combine together or split through their paths on each stage of a process. Colour is used to divide the diagram into different categories or to show the transition from one state of the process to another.
