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?

I thought Matt was talking about taking the writer from graphviz and porting it into yt.  I didn't want to write one from scratch.  That'd definitely be overkill.  But it'd be great to have a png output instead of dot -- one more automated step is less work for me :)

Wow, that's amazing stuff!
