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.
