Twitter has released another one of those animated Tweet maps created with CartoDB's Torque library. The #IceBucketChallenge map shows how the viral craze for throwing a bucket of ice cold water over your head quickly spread across the world.
As with all these animated Twitter maps you have to normalize the mapped data in your own head - and try to take into account where Twitter has a lot of users and where Twitter is not widely used. However, even taking into account the problems with these Twitter maps, the #IceBucketChallenge map is still a pretty impressive visualization of how the Ice Bucket Challenge, which started in the USA, quickly spread around the world.
That's a lot of cold people and a lot of money raised for charity.
