TED talks are often good examples of the use of graphics and visualization to convey concepts and engage the public.
I believe Hans Roseling always gives remarkable and fascinating talks thanks to the passion he puts in the story telling and -of course- to the great graphics! He shows complex historical data with gapminder, a non-profit web service displaying time series of development statistics, that makes all the data look very clear and even fun!
He provides several eyes opening talks, and another of my favorites is on Asia’s rise, where he projects the precise date India and China will reach the wealth level of U.K. and U.S.
