Gephi Layout

[giambaJ]

Hi there, I'm having some issues with the visualization of results and I'm not sure how to solve them. When running Force Atlas on Gephi, the nodes basically just converge on the center of the graph. I've tried with different parameters but the result is pretty much the same. Do you have any ideas why?

Gephi is a tricky beast to tame. There isn't a good solution that I know of to the problems that ForceAtlas has working with this type of data set (many nodes with many connections). I used a few other layout algorithms and messed with a bunch of settings in ForceAtlas to get mine to look decent. I also had to manually bring clusters in quite a bit and find stray nodes that got shot out into weird places. Sorry I can't be of more help here but its just a lot of trial and error in my experience.

No worries, I'm sure I can work this out with some more patience. Thanks for your contribution by the way, it's very interesting and you really got me interested in network analysis in general.

The layout you achieve is really amazing. Isn’t there a way to do it by software? sfdp seems to try that but it’s not the same. There are some workarounds on stackoverflow involving spliting the graph and increasing the weight of the edges, but not direct algorithm.

Edit: I found that sigma.js implemets the ForceAtlas, maybe it allows good tweaking.
