Squarified Treemaps

This has been something I have wanted to do for a while but I needed some guidance on the theory. Of course the treemap has been done a few times before (I think I saw the first implementation by marumushi I still love the design there. Since then I have seen it on a couple of other sites including CNet news). I also remember reading somewhere about someone about to release a TreeMap Flex component but I have no idea how long that will take or under what license terms. Plus I always have more trust in code I wrote since I’ll be able to debug it faster if I have to.

I am not publishing the source as yet since its needs some code cleanup, but you can look at the demo here. I have some data baked into the swf ([10,10,9,8,6,6,4,3,2,2,1]). The component then creates a series of rectangles with relative sizes reflecting the values. I have also added a redraw function listening on Stage resize, so try resizing the browser window and see how the code redraws the rectangles.

Source coming soon 🙂
