  • TreeMap is a visual representation of a data tree, where each node may have zero or more children, and one parent (except for the root).
  • Each node is displayed as a rectangle, can be sized and colored according to values that we assign.
  • Sizes and colors are valued relative to all other nodes in the graph.

Configuration:

  • We've used TreeMap class to show treemap diagram.
