Treemap

A Treemap data visualization technique is used to display hierarchical data using nested rectangles; the treemap chart is created based on this technique of data visualization.

The treemap chart is used for representing hierarchical data in a tree-like structure. Data, organized as branches and sub-branches, are represented using rectangles, the dimensions and plot colors of which are calculated.
