Sankey Diagram

The Sankey diagram shows the data flow between categories and their volume in a proportionate way. This volume is the magnitude of the relationship between these categories and is represented by arrows. The wider they are, the greater the strength of the relationship. According to the data variation, you can combine them or divide your diagram into several categories, for which you can use different colors. The arrows complete their connection through common points between the categories, known as nodes, and these connections are known as links. Therefore, the Sankey diagram is practical if you wish to visualize a diverse data mapping between two or more categories. It is also handy for representing different paths through a series of stages within a process.
