Nearly. The algorithm turns up slightly different graphs each time (and set.seed doesn't seem to make it consistent) and periodically chokes. But better than what I had. Hrm. I don't know much about the algorithm graphviz uses for dot. Do you have a reference on hand? If it's simple, I'd be willing to take a whack at it.
