We are saddened to hear about the passing away of Hans Rösling, a visionary and educator who made substantial contributions to the visualisation of data by advocating open data and illustrating trends which challenged many prejudices.
He was an impressive keynote speaker at the 30th meeting of the European Coordination Committee on Human Rights Documentation which was organised by the Raoul Wallenberg Institute in Lund, Sweden.
Watch one of our favourite presentations by Hans below, and find more inspiration on Gapminder, a foundation co-founded by Hans.
