Information is Beautiful: an interview with David McCandless

One of the most successful published data journalists in the world today, David McCandless has a new book out: Beautiful News. His work is innovative, newsy, current and incredibly popular with readers — but sometimes controversial with what he calls the "chart police".  Alberto and Simon chat with David about why he gets such Marmite-type reactions to his work, how Hans Rosling opened our eyes to the power of data visualisation and the nature of beauty. The music for today's episode is world GDP, made with TwoTone, which turns numbers into tunes.
