Nope, that was wrong too. Below is a transcript from IRC where I
was checking this out. But first:
This functionality was developed on a CentOS box where graphviz was
installed via yum. There seems to be a problem somewhere between
pydot --> GraphViz. I will be digging into this more, and hopefully
we can get is resolved quickly.
Feel free to run the python code mentioned in the transcript below
and report on your findings.
Update:
It currently seems that pydot is the problem, and one potential
solution is to use the versions of graphviz and pyparsing that were
developed with it (pydot hasn't been updated in two years).
I don't remember the versions of graphviz that CentOS installed on
the dev box, but they might have been older (and that might explain
why it worked on that box).
However, this is further complicated by seemingly inconsistent
results: Eric mentioned today on IRC that he saw it work initially
and then it stopped working -- all with recent versions of graphviz
and pyparsing.
