Back in April Google launched a search function for US public data with interactive graphing. Today, Google has made this feature much more useful with the inclusion of 17 indicators from the World Bank, including the number of internet users, life expectancy, and a host of other indicators for most of the world’s countries.

Note that this currently only works when searching google.com, not country-specific sites such as google.fr.
