Hi!

I've been using gephi for simple graphs.
I was used to use Force Directed for layout.

Now I need to represent networks of 4M nodes and 100M arcs.
I'd like to experiment with OpenOrd layout.

I need to choose the proper file format.

I think the easiest and more compact would be a CSV with adjacency list and weights.

I tried the format

a;b;0.12112
b;c;0.43;d;0.8

but values are understood as labels (nodes).

Any suggestions for a feature of adj list weighted, or how to handle this represenation?
thank you!
