Improving the Visualization of Hierarchies with Treemaps:. Controlled experiments with novice treemap users and real data highlight the strengths of treemaps and provide direction for improvement. Issues discussed include experimental results, layout algorithms, nesting offsets, labeling, animation and small multiple displays. Treemaps prove to be a potent tool for hierarchy display. The principles discussed are applicable to many information visualization situations.

Tree-Maps: A Space Filling Approach to the Visualization of. This 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.
