Gapminder

Gapminder is an independent Swedish foundation whose mission is to identify systematic misconceptions about important global trends and proportions and use reliable data to develop easy to understand teaching materials to rid people of their misconceptions. The Gapminder website has a section with multiple quizzes to test people's misconceptions about the world, data visualization tools where users can explore global trends and change over time, and a feature called Dollar Street with photos for users to see the reality behind the numbers.
