More great data visualisation stuff. Imagine taking a map of the world, and having each country as a balloon. Then, inflate or deflate the balloon until the relative areas of the countries represent some statistic about them. You get a wonderful graphical representation of that data set which is much easier to understand than a long column of figures.
Here’s the base site – some researchers at the University of Sheffield. Some pictures that I found particularly interesting were:
- Compare Net emigration with Net immigration to see where people are moving from to.
- Aircraft departures shows who is fuelling the greenhouse effect.
- Container ports is interesting just because it’s surprising.
- Compare Alcohol and Cigarettes Exports to Imports to see who makes money from slowly killing other people.
- Computers exports shows you where your PC probably came from.
They are issuing new pictures regularly. There is some source code available for a related program implementing the same algorithm; however, there’s no licence to modify. :-|
