Dr. Hans Rosling is one of my presentation heroes; he's been featured or mentioned in all my books and several times on presentationzen.com over the years.

He proves time and time again, that data are not dull—and when you are trying to change the world, there is no excuse for boring presentations. Most people are aware of Dr. Rosling through his popular TED Talks, but just in case you've never seen him present, below is a nice 5-minute piece he did on CNN's Fareed Zakaria GPS.
