Google Analytics team today announced that as of this week's release, you can now see region level maps of over 170 countries!
To try it out, simply go to the Location report (under Visitors > Demographics) and click a country. We'll try France:
We can see at a glance that Ile-de-France sends the most visits to our site. To see cities, just click City in the Viewing: list immediately below the map. Once you're on the cities view, you can try out another feature we rolled out recently -- a magnifying glass that appears when cities are clustered closely together.
P.S. Did you know you get map overlay in more places than just the Visitors > Demographics > Location report? Take a look at the tab on the Visitors > Technology > Mobile report.
