OK here's my problem, I'm generating a graph of a python module, including all the files with their functions/methods/classes.

I want to arrange it so, that nodes gather in circles around their parent nodes, currently everything is on one gargantuan horizontal row, which makes the thing >50k pixels wide and also let's the svg converter fail(only renders about the half of the graph).

I went trough the docs(http://www.graphviz.org/doc/info/attrs.html) but couldn't find anything that seems to do the trick.

So the question is:
Is there a simple way to do this or do I have to layout the whole thing by myself? :/
