Interactive data charts available from Google

Still somewhat limited in their coverage but great fun to play with, you can now find population or unemployment data for states and counties and then interact with the data (do comparisons across counties, states, to the whole U.S., etc.). This is a Google search tool imposed on Bureau of Labor Statistics and U.S. Centus data. Go to Google's regular search screen (Google.com) and enter, for example, population nevada or unemployment rate clark county
Here are some sample graphs:

Thanks to librarian Michael Yunkin for bringing this to my attention! I'll add this to the "Statistics and Demographics" tab of the Education subject guide, too.
