Did you check-in to Foursquare on both ends of a trip over Thanksgiving or Christmas last year? If so, you're probably somewhere on this infographic.
Foursquare (it's a website and mobile app that keeps track of places you visit) collects a lot of data on a lot of different people.

Each one of those colored lines represents a trip by either plane or train, while the white dots show travel by car. The graph along the bottom shows how travel volume changes during November and December.
