FN ISI Export Format VR 1.0 PT J TI Trees in a treemap AF Burch, Michael Diehl, Stephan AU Burch, M Diehl, S AB This paper deals with the visual representation of a particular kind of structured data: trees where each node is associated with an object (leaf node) of a taxonomy. We introduce a new visualization technique that we call Trees In A Treemap. In this visualization edges can either be drawn as straight or orthogonal edges. We compare our technique with several known techniques. To demonstrate the usability of our visualization techniques, we apply them to find interesting patterns in decision trees and network routing data. DI 10.1117/12.643272 ER
