Treemap

Treemap is a space-constrained visualization of hierarchical structures. It is very effective in showing attributes of leaf nodes using size and color coding. Treemap enables users to compare nodes and sub-trees even at varying depth in the tree, and help them spot patterns and exceptions.Treemap was first designed by Ben Shneiderman during the 1990s. For more information, read the historical summary of treemaps, their growing set of applications, and the many other implementations. Treemaps are a continuing topic of research and application at the HCIL. For more information visit http://www.cs.umd.edu/hcil/treemap/
