TreeMap

Description
The 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 composing treemaps is highlighted based on the quantitative value of the corresponding data point.
The main advantages of treemap charts conclude in allowing us to do the following:
  • identify the relationship between two elements of a hierarchical data structure;
  • optimize the use of space;
  • accurately display multiple elements simultaneously;
  • show ratios of each part to the whole;
  • visualize attributes by size and color coding.
