TreeMaps

Treemap is a unique method for visualizing data in a two-dimensional display. The technology organizes hierarchical data as nodes, giving more space to nodes which are more relevant or important—for example, making the most relevant results of a search appear larger in the window. Users can change the program’s settings to customize preferences such as how space is allocated and how individual nodes are colored. The Treemap technique was developed jointly by Dr. Ben Schneiderman of the Human Computer Interaction Lab and Dr. Catherine Plaisant-Schwenn of the Institute for Advanced Computer Studies at the University of Maryland College Park. Gudger believes Treemap technology has the potential to be on every desktop in five years.
