About This MicroSim

This MicroSim ranks the same provider referral network four different ways so you can see that "importance" has several meanings. Degree centrality finds busy hubs; betweenness finds bridges that connect otherwise-separate clusters; closeness finds providers well-positioned to reach the whole network quickly; and PageRank finds providers who are influential because they connect to other influential ones. Node size and shade encode the selected measure, computed live on the graph.

How to Use

Switch the centrality measure in the dropdown and watch the node sizes, shading, and top-5 ranking change for the very same network. Compare measures: the high-degree hub dominates Degree but a low-degree bridge node jumps under Betweenness, and the densely-embedded node leads under Closeness and PageRank. For PageRank, adjust the damping slider to see its effect, and use the definition box to choose the right measure for a given question.
