Graphs

[Aqlor]

Hey.
I was wondering, what program do people usually use to draw graphs? I mean the graph theory kind of graphs.
I've read about GraphViz but I think I needed something more advanced. I need a program that can show me the visualization of graphs, and that will change colors of the connections that I want to.
Anyone knows any program?
Something with 3d would be great but isn't needed.
Thanks.

I think Openoffice calc has the 3D graphs,
but if you have KDE i think the best is Kchart really nice graphs,
:)

GraphViz uses a graph file language called DOT to define graphs. You can render this graphs using different algorithms. It's not interactive.

DOT lets you define colors for given edges and nodes, see the dot manpage (http://manpages.ubuntu.com/manpages/karmic/en/man1/dot.1.html) and the GraphViz documentation page (http://www.graphviz.org/Documentation.php).

I don't know if that's want you want.

Oh, I didn't knew that edges could be colored too using graphviz. That was exactly was I was looking for. Thanks, its solved
