graphviz or hypergraph

When making these images about modules i use graphviz to render them. But just ran into http://drupal.org/project/hypergraph which looks great. So I have to study this one! Commands to render a .dot file are ie with non overlapping nodes

neato -Goverlap=false -o my.neato.png -T png my.dot

or for a top down graph.

dot -T png -o my.dot.png my.dot

The attached image is an installation with the jstools, cck, views, drush, og in order to get faster user experiences. View the full image
