Treemap Chart

Treemap Chart is intended for the visualization of hierarchical data in the form of nested rectangles. Each level of such a tree structure is depicted as a colored rectangle, often called a branch, which contains other rectangles (leaves). The space inside each of the rectangles that compose a Treemap is highlighted based on the quantitative value in the corresponding data point.

The main advantages of Treemap Charts conclude in allowing us to do the following:

• identify the relationship between two elements in a hierarchical data structure,
• optimize the use of space,
• accurately display multiple elements together,
• show ratios of each part to the whole, and
• visualize attributes by size and color coding.
