Here's yet another reason to love statistics and data: Hans Rosling's incredible talk at the 2009 TED Conference using data presented in graphical form by GapMinder, a non-profit seeking the "
Rosling uses Gapminder data - which are online and fully interactive - to make the case that prevention, not treatment, is the way out of the HIV/AIDS pandemic. He also shares provocative graphics highlighting between- and within-country variability in HIV prevalence rates.
