How would I create the following graph with D3? I don't know the name for this type of visualization, and the closest I could find were "force-directed" graphs.
Legend: Filled nodes are people, non-filled nodes are attributes (e.g. favorite color).
This is my version: http://jsfiddle.net/doraeimo/JEcdS/embedded/result/ which is easy to show system performance and network flow.
