New from Google Labs, ​"Google Public Data Explorer" makes large datasets easy to explore,
visualize and communicate. As the charts and maps animate over time,
the changes in the world become easier to understand. You don't have
to be a data expert to navigate between different views, make your own
comparisons, and share your findings.

embed them in their own webpages. Embedded charts and links can update
automatically so you’re always sharing the latest available data
