Hi Stephen & John,

Sorry, I didn't mean to output pngs directly -- I just meant, a single
place we could write hierarchical datasets to dot format.  There's a
lot of research, time, development and wheels in graphviz that we
don't need to reinvent.

As for a new package, I wonder if maybe that decision would benefit
from a cost/benefit analysis: how much of any given graphviz wrapper
would we use?

Is graphviz not capable of doing something we need? I can see that it would be slightly more convenient to skip an intermediate step, but I think it would be lots of work on our part, when people have put at least a decade already into graphviz. Perhaps I misunderstand you?
