I am currently trying to visualize the network of a moderately big forum: Users who post to threads. In Gephi I only managed to created blobby hairballs, any suggestions for other free tools? It's a couple of thousand users and a couple of thousand threads but pretty dense.
BioFabric should be able to handle that OK. Import as tab-delimited sif file. Default layout is breadth-first search, in order of decreasing degree, starting from highest degree node. If that is not what you want, can specify node order. See this post: http://biofabric.blogspot.com/2013/05/banish-bipartite-blues...
