If you live in a big city, you'll know that there's a heartbeat to life there: from the early morning commuters, do the workaday life in the central business district, to Happy Hour, to restaurants, to late-night drinks, to the true night owls that prowl the street late at night. FourSquare have done an impressive job of capturing the pulse of that heartbeat, with these data visualizations of check-ins over a 24-hour period. Here's San Francisco:
I used to live in San Francisco, and this really captures a day in the life there: commuters flowing in from the Eastside in the morning, tourist traffic on the ferries during the day, the swell of office workers in the Financial District and downtown flowing to an evening out into the clustered bar/restaurant districts in the Haight, Castro, Noe Valley and elsewhere. You can also see the pulse of other large cities, including London, Tokyo and NYC.
Enjoy your weekend -- and if you check in while you're out, know that you're contributing to beautiful visualization projects like this. We'll be back on Monday.
