Path (graph) shower utility

[Durumdara]

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

Sure. 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.

Thank you Jorgen, now I understand the question, and the answer isn't
difficult

Graphviz is good enough for this purpose.

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:

There are other libs around, I have seen a new one quite recently.

Perhaps that one was:

Yapgvb,
a Python wrapper around the AT&T's graph layout library Graphviz.
