Recommended podcast: Hans Rosling on data visualization (19:50)

In this data visualization classic, Hans Rosling applies his visualization tools to data on life expectancy, fertility rate, GDP, infant mortality, etc. His tools present data dynamically -- we see changes over time -- and he is a dynamic, funny speaker as well.

The talk ends with visualization of some Internet penetration data and a plea for open access to government data.

The talk is immodestly titled "The best stats talk you've ever seen," but it delivers what it promises. If you are hooked, you can interact with his tools and follow him on his Website.
