# SciDAC Collaboration Graph

**This graph is interactive. Use your middle mouse wheel to zoom in on the graph (or the buttons located on the bottom right corner).**

This graph was generated by looking at the different groups of PIs on all SciDAC-2 projects. The graph was trimmed by removing the leaves. The colors of the graph represent the different communities (modularity) found by the graph tool (Gephi and Sci2) [See:Vincent D Blondel, Jean-Loup Guillaume, Renaud Lambiotte, Etienne Lefebvre,
