If wha'ts most alive is pydot-ng that's fine with me.

One of the reasons taskflow went with pydotplus is that it's used in the 
larger networkx graph library (which taskflow happens to use for its 
internal workflow graph):

https://github.com/networkx/networkx/blob/master/networkx/drawing/nx_pydot.py

Which if u see in the taskflow code is just what's being called into:

https://github.com/openstack/taskflow/blob/master/taskflow/types/graph.py#L59

But if pydot-ng is more 'healthy' I'm fine with adjusting a few things 
and using that (and submitting a PR to networkx to get them to use 
pydot-ng).

If fuel used networkx @ https://github.com/networkx/networkx that'd be 
even better (in general if anyone is using graphs in there app, networkx 
seems to be the best library for that kind of stuff that currently 
exists) ;)
