As the amount of data fueling the information age grows exponentially, we need new ways of making sense of all that information. Data visualisation is an art form for the twenty-first century; it takes all the results of all our science and politics and everything else, and it reorganises them visually so that relationships are clear and interpretations possible. So much more is possible than the pie charts and bar graphs of yesteryear.

David McCandless is a master of data visualisation. In this TED talk he shows us some of his work.
