Hi, I have a question about extracting data from the internals of GraphPlot. For example, the following code plots multiple subplots of disconnected clusters. << DiscreteMath`GraphPlot` n = 129; d = Table[i -> Mod[i^2, n], {i, 0, n - 1}]; GraphPlot[d]; However, I would like to know the subsets that are being plotted. I know you can plot the vertex labels on the chart, but my dataset is ~50,000 connected vertices and GraphPlot outputs ~100 clusters, so vertex labeling is unrealistic. It would be very interesting to know which vertices GraphPlot has associated. There maybe a way to do this using some functions from "Combninatorica" but I have not been able to find them. Can anyone help? Thanks, Matt
