InfoVis 2003 Contest Submission: Visualization and Pair Wise Comparison of Trees Treemap, Radial Tree, and 3D Tree Visualizations

This paper presents and discusses data analysis and visualization results as part of our InfoVis 2003 contest submission. Two inhouse developed approaches – a coupled dual radial tree layout interfaces and a three-dimensional tree viewer (Stewart, Hart et al. 2001) – were employed to compare phylogenetic trees. An inhouse developed radial tree layout was applied to visualize tree topology. The treemap algorithm (Bederson, Shneiderman et al. 2002) developed at HCIL, University of Maryland was utilized to visualize tree attributes.
