It has been announced today that the great Dr Hans Rosling has died at the age of 68 after a battle with pancreatic cancer. He was well-known for promoting statistics and the use of data to explore development issues.
Rosling made several presentations including TED talks. One of his best presentations was on comparing life span with wealth in 200 counhtires over 200 years. It is a brilliant piece of Data Visualization and his love for data shines through. Worth another look.
