This is great!!! I see what you mean about the layout issue, but if I have
some time tonight I will experiment with the algorithm I have in mind to see
if it will work. This little "quickie" is a great start, though!

I've played around a bit with Simulated Annealing and the Aglo layout
algorithm. I had a problem (probably simple math) with scaling the
various forces so that the graph would lay out nicely. I could send
you the code I've done already if you want.

As an example of how easy it can be to generate graphs using
Connectors, the attached change set is a quickie that will draw class
shapes and inheritance relationships for categories, change sets, or
hierarchies.
