Figure 1. TreeVersity comparison interface. On the top are the two original trees being compared (budgets for 2011 and 2012). At the bottom the DiffTree shows the amount of change for each node. The glyph called "the bullet" points up to denote increases, and down for decreases. Nodes that have the same value in both trees are shown as small gray(More)
Transportation datasets of all kinds are hierarchical in nature, and therefore easily represented in tree structures. Visually comparing the changes in these hierarchical datasets over time can be extremely difficult, even when the trees are relatively small. TreeVersity is a novel interactive visualization that allows users to detect and analyze changes in(More)
