I had run into GapMinder some time ago, but was reminded of it when I encountered this talk that Ola Rosling gave at Gov 2.0 Summit that really makes it clear how the visualization of data — especially visualizing data over time — can give us valuable insights into trends in the physical and social world(s). Their Trendalyzer software is used by Google…as you’ll see in this presentation.
 Ola Rosling is at Google, Inc. and involved with data visualization. His father, Hans Rosling, founded GapMinder.org which provides online tools and data for data visualization. The team from GapMinder now works for Google and Hans’ original foundation is focused on providing and analyzing data. “Gapminder is a non-profit venture promoting sustainable global development and achievement of the United Nations Millennium Development Goals by increased use and understanding of statistics and other information about social, economic and environmental development at local, national and global levels.”
