Data Visualization: World travel and communications recorded on Twitter
By Eric Fischer
Green is physical movement from place to place; purple is @replies from someone in one location to someone in another; combining to white where there is both.
Reported trips to Null Island excluded; all other geotags trusted. Endpoints of trips are real data; routes in between are fabricated.
Data from the Twitter streaming API through September 1, 2011. Continent shapes from Natural Earth.
