The Voronoi Treemap is a space-filling treemap technique that relaxes the constraints of rectangular nodes. Its organic shapes maintain a one-to-one aspect ratio, are flexible with their placement, allowing stable zooming and dynamic data values. This poster articulates the tradeoffs that go into generating dynamic treemaps. We then present innovative features that allow Voronoi Treemaps to smoothly represent dynamically-changing data. We demonstrate its use with a deep organizational chart and an animated dataset. User tests confirm that Voronoi Treemaps can be a successful visualization technique.
