highlighting clusters or subtrees in graphViz

I want to highlight various sub-trees in a given tree using different colors. e.g. consider binary tree below (I could show the edges between parent and its children)

                      0

             00               01

        000     001     010        011

The task is to draw two convex/concave hulls showing 00, 000, 001 in one cluster and rest of the nodes(0, 01, 010, 011) in another cluster. GraphViz has subgraph feature which allows recta开发者_JS百科ngular regions but how to highlight these non-rectangular regions.

In reality my original tree will be much bigger with more clusters. However, each cluster can physically be put into one convex hull.

Can I do this in graphViz or with any associated addons. Otherwise, are there other tools available to do this?

How about gvmap?
