Abstract: Displaying a comprehensive data overview is one of the most challenging tasks in visual analytics. Methods to achieve this are, for the most part, dependent on the type of the data and the motivation for analysis. The Recovery Act report dataset includes two intrinsic hierarchies, both of which should be included in any overview display. Treemaps have proved very useful for displaying hierarchical data. We present a tool which synchronizes between two treemaps and implements a novel approach to highlighting corresponding nodes across the treemaps. Interesting explorations can be saved and compared in further analysis.
