v0.4.0 In windows 7 and FF 14.0.1 leaf nodes are not rendered in example tm in index.html. Geometry is created and can be seen via the highlighter as mouse moves across canvas. FF console shows no errors.

When mousing out of map, node and group highlight boxes appear in wrong position and scaling.

Evan,

As I'm looking at the code, I'm noticing that there isn't a lot of functionality right now being provided by jQuery. If you don't deliver this as a jQuery widget, it might make it easier to break up the code into separate files (to be combined and minified as part of a build using something like Anvil - https://github.com/arobson/anvil.js) and implement support for AMD and CommonJS (see https://github.com/rniemeyer/knockout-kendo/blob/master/src/knockout-kendo.js as an example that supports AMD and CommonJS and uses Anvil).

Thoughts?

Addition of the animated size by transitions has broken the treemap events treemapmousemove and treemapclick. Believe its something to do with how events are bound/unbound to the treemap widget's canvas element.

If user mouses over index.html's example treemap during a size by transition animation the ghosted node's future location gets highlighted. Treemap events should be temp disabled during transition animation.

When i try to squarify 100 equally weighted Nodes, they are rendered quite good! I like it more than googles version https://developers.google.com/chart/interactive/docs/gallery/treemap or various other libraries i have testetd so far ...

But ...

The very last one in the bottom/right corner gets calculated so, that in most cases it will seem a totally different value.
