Project description

TreePlus is an interactive graph visualization system based on a tree-style layout. TreePlus transforms graphs into trees and shows the missing graph structure with visualization and interaction techniques. For example, TreePlus previews adjacent nodes, animates change of the tree structure, and gives visual hints about the graph structure. It enables users to start with a specific node and incrementally explore the graph. TreePlus was inspired by the success of our earlier tools, SpaceTree and TaxonTree.
