Dunno. Suck it and see. I've had varying success with different layouts for different graphs. I find graphviz to be really slow for large graphs.1. What is the best layout for a gv file that has 17444 nodes and 18068 edges
Don't forget that gephi has a lot of really good layout plugins in the box, too.
Currently, there is none. I've never used or heard of it, so I didn't think to include it in my code.2. What is gephi way of doing Graphivs ccomps - command line ccomps -zX# -1000
Because it's not in your path. Either add the full path to the "dot" binary to your path, or edit the "dot binary" option in the graphviz layout to include the full path, plus executable, to dot.3. Why will the Graphviz Plugin not find my installed Graphviz
I'm assuming you're on windows, so best bet for adding it to the path is to hit windows-break, go into advanced system configuration settings, and edit your PATH under "environment variables".
