attributes not allowed in edges

[GoogleCodeExporter]

It is not possible to use attributes in edges
(http://www.graphviz.org/doc/info/attrs.html).

GvGen solves this with

graph.propertyAppend(postman, "color", "red")

I whink that for python-graph it would be nice to have:

add_edge(self, u, v, wt=1, attributes=None)

where attributes could be a list of tuples like [("color", "red"),
("penwidth", 4), ...]

I'm sorry, but python-graph is not meant to be a graph drawing tool, but an 
graph
algorithm library. Basic drawing support is provided, but that's all. What you 
are
asking for goes against the purpose of this library. I usually like to add the
features people request, but I'm afraid I'll have to let this one pass.

If you need more sophisticated and refined drawings, you are surely much better
served by GvGen or by any other tools specialized in this task. At worst, if you
really need both algorithms and customizable drawings, you could easily 
translate
python-graph graphs to GvGen. If you do so, I'll be happy to add your code to 
the
wiki so other people can benefit from it too. Also, I would not mind helping 
you with
this (just drop me a mail or join our development group/mailing-list).
