Hi,
Treemap is a map. And a map works well when it provides a background onto which we can emphasize certain things.
So, I want to be able to emphasize various points in the tree map based on some property. Normally, I can achieve this by specifying things like fillColor, or borderColor. However, in the current implementation of the treemap, this does not work because the layout overrides possible custom colors because it uses hardcoded colors denote nesting level.
At least the border should be highlightable, but I think we can do more (for example, we can denote nesting level by border width).
Cheers,
Doru
