Hans Rosling, famous for his lectures which explore enormous amounts of public data and presents it in a storytelling fashion, presents data on 200 countries in 200 years. Weatherman and sports commentators can step aside as Hans presentation style is both exciting and engaging and for the first time steps it up with the use of augmented reality. In this video Hans shares the story 200 countries have moved from being poor with low life expectancy to wealthy and high life expectancy using over 120,000 data points in the process.

David McCandless, award winning designer, writer, and author, speaks at TED on his passion for exploring data and creating meaningful visualizations that convey information in the form of a story. With a plethora of examples from his latest book, Information Is Beautiful, the talk is both facinating and inspiring. In one example he displays the carbon output from the Icelandic volcano that grounded thousands of flights over Europe in 2010. By comparing the carbon output that those flights would have produced themselves, the eruption was the first carbon-neutral volcanic event the world has seen. David posts his visualizations on his website and it is worth diving in to take a look.

Dan Hill, designer and urbanist, talks at Interaction ’10 about urban landscapes and the information that inhabits them. Dan loves to identify all of the data points that are embedded in cities and expose them through meaningful ways. In this video, he provides a wonderful tour of the many projects that he and others have worked on. After watching the video, it is difficult to ignore the pervasive bits of information that you once passed by without ever considering how exposing them might change people’s behaviors.
