You want graphviz: http://www.research.att.com/sw/tools/graphviz/ It's primarily a tool for rendering a graph (in Postscript, PNG etc) from a text representation, but IIRC there are Python bindings for it as well. Lots of people use it for purposes similar to yours. /Jorgen -- // Jorgen Grahn grahn@Ph'nglui mglw'nafh Cthulhu \X/ snipabacken.dyndns.org R'lyeh wgah'nagl fhtagn! -- http://mail.python.org/mailman/listinfo/python-list
Re: Path (graph) shower utility
Thank you Jorgen, now I understand the question, and the answer isn't difficult :-) Graphviz is good enough for this purpose. but IIRC there are Python bindings for it as well. Durumdara can use an email module to extract data, then a graph library to create the graph, and then save the result in dot format for Graphviz. My Graph is probably enough: http://sourceforge.net/projects/pynetwork/ Otherwise NetworkX is good: https://networkx.lanl.gov/ There are other libs around, I have seen a new one quite recently.

Path (graph) shower utility
Hi !
I need to create a program that read eml file headers, analyze the
receive tags and create a path database. I finished with this program
section.
But I want to show a graphical summary about the paths.
This is (what I want to show) like a graph - show ways, stations, etc,
and I want to show the strength of lines (how many of mails use this way).
Can anyone known about a freeware tool, software, or python module that
can show graphs with best alignments ?
Please help me. Thanx for it:
dd
Ps:
The OS is Windows XP:
I tryed with pydot, but this code created many 0 length files.
import pydot
print pydot.find_graphviz()
edges=[(1,2), (1,3), (1,4), (3,4)]
g=pydot.graph_from_edges(edges)
g.write_svg('graph_from_edges_dot.svg', prog='dot')
g.write_svg('graph_from_edges_neato.svg', prog='neato')
g.write_jpeg('graph_from_edges_dot.jpg', prog='dot')
g.write_jpeg('graph_from_edges_neato.jpg', prog='neato')
{'fdp': 'c:\\Program Files\\ATT\\Graphviz\\bin\\fdp.exe', 'twopi':
'c:\\Program Files\\ATT\\Graphviz\\bin\\twopi.exe', 'neato':
'c:\\Program Files\\ATT\\Graphviz\\bin\\neato.exe', 'dot': 'c:\\Program
Files\\ATT\\Graphviz\\bin\\dot.exe', 'circo': 'c:\\Program
Files\\ATT\\Graphviz\\bin\\circo.exe'}
Thanx for help: dd
