sage: sage.graphs.generic_graph.GenericGraph.layout_graphviz?
...
This requires ``graphviz`` and the ``dot2tex`` spkg. Here are some
installation tips:
* Install graphviz >= 2.14 so that the programs dot, neato, ...
are in your path. The graphviz suite can be download from
http://graphviz.org.
* Download dot2tex-2.8.?.spkg from
http://trac.sagemath.org/sage_trac/ticket/7004 and install it
with ``sage -i dot2tex-2.8.?.spkg``
Speaking of which: I never got feedback on my request to put this spkg
in optional/experimental:

your wish to have it as standard most probably is not possible, due to
licensing of graphviz...

Thanks Dima, that's at least a piece of feedback :-)
So, if no one seems to care, does this mean that this is implicitly
generally accepted as an optional package?
Vote:
[ ] Yes!
[ ] No!
Cheers,
Nicolas

Does it build on all supported platforms?

It's plain python, so I assume that this should be safe.
Best,
Dr. David Kirkby
It would not be the first time plain Python has failed on one system or another.
