[SOLVED] weight on node

[florent.hautefeuille]

Hello
I use Gephi to try to make representation of old cadasters. My nodes are parcels and my edges are links of neighborood betwenn 2 parcels. When I use forceatlas I obtain a representation with a big distorsion. If one parcel have a lot of neighbors, it draws all the parcels around against it (cf fig). Then I obtain a "colony of sea urchins" instead of having a regular landscape of parcels. I try to understand how I could attribute to each parcel a weight (in fact his surface) and that the algorythm take in care this weight to organise the graph.
Thank's a lot

As far as I know, there are very few, if any, layout algo which can take nodes attributes as parameters to determine say, repulsion or attraction forces. Your research question shows that it would be a nice thing to develop!

So, is anybody for the task?

It could consist in taking the ForceAtlas algo, and add an attribute of nodes as an additional parameter for repulsion or attraction. Ideally, this attribute could be selected in the parameters of ForceAtlas, as a dropdown menu, and it would also be possible to determine the intensity of this attribute.

Java developers, help us!

Best,

Clement

I think Visone has this feature it would be interesting to know how they are doing it. Any academic paper on this topic would also be welcomed, to better define specifications.

Thank you for explanations. As I'm not able to make java developments, I will try Visone.
