Treemap
[Johnson and Shneiderman, 1991]
Treemaps [Johnson and Shneiderman, 1991] are a rectangular, space-filling approach for visualizing hierarchical data. They use 2D visualization of trees where the tree nodes are encapsulated into the area of their parent node. The size of the single nodes is determined proportionally in relation to all other nodes of the hierarchy by an attribute of the node.
