Tree Map
Tree Map charts are used to display large amounts of hierarchical data. When users want to view all of their hierarchical data at one time, tree maps can be used. Each rectangle represents a branch in a tree and it also shows how much data it comprises. The size and position of the rectangles are based on the quantitative variable used for the chart. Patterns across the data can be identified using the size and color of the rectangles.
