Power mapping
Mapping the interlocking directorate of American political institutions: the people who sit at more than one organization, and the ties that connect them.
LittleSis Atlas → Search 108,278 people and organizations, and see who each one is tied to. Works on a phone. Power Map → The densest 3,790 entities as one graph. Pinch to zoom, tap a node to follow it. Built for a phone. The same graph in Retina → Filtering and clustering that the map above doesn't do. Best on a desktop: Retina puts its controls in a sidebar that crowds out a phone screen. littlesis.gexf → The same slice as a file. Opens in Gephi, which handles far larger graphs.
