Google has expanded their ‘public data search feature’ they announced a while back with several new datasources, and connected it with a new interactive visualization tool they call the ‘Public Data Explorer’.

With a handful of data providers, there are already billions of possible charts to explore. We currently provide data from the same three providers currently available in our search feature: the World Bank, the U.S. Bureau of Labor Statistics and the U.S. Census Bureau. In addition, we've added five new data providers: the Organization for Economic Co-Operation and Development (OECD), the California Department of Education, Eurostat, the U.S. Center for Disease Control, and the U.S. Bureau of Economic Analysis. We're excited that all around the world new data providers are deciding to make their information freely available on the Internet, enabling innovators to create interesting applications, mash up the data in new ways and discover profound meaning behind the numbers.

One such visualization is this “Life Expectancy vs Fertility” visualization.

Impressive stuff. If you create a visualization, post a link in the comments!
