We start with Bostock's Multi-Foci Force Layout example and add motion to represent traffic progressing through a system. Think of this as progress bars for every inflight transaction.

Each dot represents a transaction read from a four-minute long recording. Watch for a spike in activity at 20:20 after the hour. The animation repeats when finished.

Dots enter when transactions start and exit when completed. Their speed is proportional to client's response time while their size reflects the server's contribution to total time. Color comes from the specific request.

We simulate push-pins marking locations on a map. We use Force layout to position the pins as close to where they belong as possible. This may not be very close in geographic terms. However, the energy minimizing placement looks sensible on maps of large regions with densely clustered locations.

Wiki appears as a word in the New York Times crossword on June 30, 2013. Thanks to David DiNucci for bringing this to my attention and to Bill Butler for posting the puzzle with explanation.
