In this TED talk by David McCandless, he shows and explains examples, that turn complex data sets (like worldwide military spending, media buzz, Facebook status updates) into beautiful, simple diagrams that tease out unseen patterns and connections. Good Data Visualization, he suggests, is the best ways to compress knowledge and it may just change the way we see the world. Quoting Hans Rosling, “Let my dataset change your mindset”.
