Hans Rosling built an unlikely following for a professor of international health: television audiences who watched him narrate decades of global development data as if it were a sporting match. The film follows Rosling through the Gapminder project, the software he co-founded to turn UN statistics on population, income, and disease into moving bubble charts, and into the lecture halls and TED stages where those charts made him a public phenomenon. Interviews and footage trace how a Swedish physician who spent years treating outbreaks in rural Africa ended up using childbirth-mortality curves and box-office props to argue that the world was getting better than most people assumed, and that ignorance about basic facts crossed education levels and professions. The film shows him testing chimpanzees against university students on the same quiz questions, sword-swallowing on stage, and needling journalists and executives about their assumptions. It is a portrait of a statistician who treated data visualization as a performance, and who thought public misunderstanding of global progress was itself a problem worth fixing.
