This graph visualize a coauthorship network of scientists working on network theory and experiment, as compiled by M. Newman in May 2006 (M. E. J. Newman, Finding community structure in networks using the eigenvectors of matrices, Preprint physics/0605087).
The network was compiled from the bibliographies of two review articles on networks, M. E. J. Newman, SIAM Review 45, 167-256 (2003) and S. Boccaletti et al., Physics Reports 424, 175-308 (2006), with a few additional references added by hand. The version given here contains all components of the network, for a total of 1589 scientists, and not just the largest component of 379 scientists previously published.
