Unusual Data Visualization Tools

The Boston Marathon is visible in Google Maps’ traffic view. The road is closed for the runners, and the runners are going slow, at least relative to a car, so they show up as a huge traffic jam on the race route. All the other roads are in good shape because Race Day/Patriots’ Day is a state holiday, and so everyone is home from work. It probably also helps that it’s a gorgeous day out, and so no one wants to be in their car.
