Hans Rosling was a renowned physician, academic, and public speaker. His presentations were grounded in solid statistics, illustrated by Gapminder, a breakthrough visualization software he developed together with his son and daughter-in-law. The animations transform development statistics into moving bubbles and flowing curves that make global trends clear, intuitive, and even playful. During his legendary presentations, Rosling took this one step farther, narrating the animations with a sportscaster's flair.
