From Foursquare Analytics:

Every day, millions of people check in on Foursquare. We took a year's worth of check‑ins in Istanbul, London, Chicago, Tokyo and San Francisco and plotted them on a map. Each dot represents a single check‑in, while the straight lines link sequential check‑ins.

What you can see here represents the power of check‑in data — on Foursquare, every city around the world pulses with activity every hour of every day.
