Hi Yannis,
As the error message states, that is happening within your code at line
459. It isn't going down to graph_tool or graphviz.
And it is a python NameError for 'label', so you're simply using a name
'label' that is not defined.
You can't define a dictionary using as argument something that is not
defined.
In this case it is your dictionary definition that should have quoted the
name so it becomes a string.
Try this instead:
graphviz_draw(g, vcolor=typev, vprops={"label": labelv}, eprops={"label":
labele}, output=fname+".pdf")
Good luck,
ale
