Graph API / framework

[George Sakkis]

Does anyone know of a good graph API ? The only one I found for Python is
part of kjbuckets
(http://starship.python.net/crew/aaro...jbuckets.html),
but I was looking for something more sophisticated; I am more concerned
about elegance and extensibility than top performance. JUNG
(http://jung.sourceforge.net/doc/manual.html) for java looks more promising.
Does anyone have experience with it or some other relevant framework ?
Thanks,

George

You might want to review ReportLab. It has a
very nice graphing API.

Re: Graph API / framework

The best package I've seen for doing Python API graphs is matplotlib.

However, I think what the poster is looking for is not x-y graphs,
but discrete (i.e. node/link) graphs, and for that I don't have
a suggestion. Pretty easy to put something together using
dicts, though.

is something like pydot (http://dkbza.org/pydot.html) what you are
looking for? Bindings for the dot tool from the grapviz package

You'd probably just want to implement it yourself. There are some basic
python graph examples out there, like this one:

http://www.ece.arizona.edu/~denny/python_nest/graph_lib_1.0.1.html

http://www.ece.arizona.edu/~denny/python_nest/graph_lib.py

For drawing graphs, people tend to use Graphviz from python, but you
could draw it yourself using a GUI toolkit like wxPython.

Or else use Jython to access some of the Java libraries like Jung or JGraph.

If you find any better options, please share them here,
