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)
A common data analysis task is to compare pairs of trees to detect changes in leaf or interior node values and to identify created and removed nodes. However even in trees with just a dozen nodes it is difficult to find those differences. We present TreeVersity, a new interactive visualization that gives users powerful tools to detect both node value(More)
When comparing two trees, the most common tasks are to identify changes in the node values and to identify topological differences. However even in trees with just a dozen nodes it is difficult to see those differences. TreeVersity is a novel interactive visualization that allows users to detect both node value changes and topological differences.(More)
