Johnson, BrianShneiderman, BenThis paper describes a novel method for the visualization of hierarchically structured information. The Tree-Map visualization technique makes 100% use of theavailable display space, mapping the full hierarchy onto a rectangular region in a space-filling manner. This efficient use of space allows very large hierarchies to be displayed in their entirety and facilitates the presentation of semantic information.
