a novel treemap data visualization approach that uses Voronoi tesselations (a polygon-based subdivision algorithm) instead of rectangular shapes. it attempts to avoid the problems with the aspect ratio of the rectangles as well as with identifying the visualized hierarchical structure. this approach allows for creating treemap visualizations within areas of arbitrary shape, such as triangles & circles (& in addition is also quite aesthetic).

Too cool...
I have to say that I've been interested in treemaps for some time now. But I can't help but think that while they are really neat, they may never be practical for mainstream applications.

voronoi fractals rule - how excellent to come across this post.
Good job finding this! The voronoi treemap is a brilliant idea. It will interest you to know that we have done an web version of it for a Swedish art exhibit at www.liljevalchs.com (with permission from Konstanz of course).
that is one badass algorithm.
I think this research on Voronoi treemaps is a significant advance and a major contribution.
