Prof. Hans Rosling (Karolinska Institute--International Health) spoke at Cornell recently. His talk made palpably clear why he is the most plausible successor to Prof. Tufte's legacy forged by his seminal The Visual Display of Quantitative Information. Rosling's 20-minute Ted Talk, described as "the best stats you've ever seen," has been viewed almost 9 million times. But the most comprehensive archive of Rosling's work is found at the Gapminder website (here). Setting aside the raw aesthetics of Rosling's presentation of data, his substantive task involves bringing data to trendy hypotheses about world macro trends. Seriously folks, while not necessarily "legal" in the narrow sense, this is nonetheless worth a look.
