Use the navigation controls to change the map:
- to pan the map, hold the left mouse button down and drag the map around
- to zoom in and zoom out, use the "+" and "-" symbols in the lower right

Click on a push-pin to view the city, state and number of visitors from that city.
The initial zoom level does not cover all our visitors (from Washington to Ohio, and Minnesota to South Texas!)
Zoom out to get the 'big picture'.
