Hi Peter!

Any news about the GraphViz layout?

Cheers,

Hi Alexandre,

In a wonderful world, I would like:
- a real graph layout (like in graphviz) that can take into account around hundred nodes and several hundred of edges and place the nodes in order to see something. Currently, I have to use the circle layout and it looks strange.

Unfortunately making real graph layouts is really hard issue�� I've wrote my bachelor thesis about this and didn't get very far; it's bit of a nightmare if you don't have good foundations. :'(

In any case, I wrote a simpler layout delegator in Roassal that delegates the layouting to graphviz and it works reasonably well, so I could probably add it to Roassal (you however need graphviz installed and it would add another dependency to Roassal, which I'm not so keen on).

Maybe also OGDF (http://ogdf.net/doku.php) could be used if you are ok with GPL�� they have their own graph format so there could be some interaction.
