Minneapolis Crime on Google Maps

The Twin Cities Crime App is a really good example of how to visualize crime trends using Google Maps.

On initially loading the map the user is presented with a map of St Paul, Minneapolis. Neighborhoods on the map are shaded red or green to show where the weekly crime rate has risen or fallen. Users can then click on each neighborhood on the map to view all crimes for the week plotted on the map.

The Crime App includes a date control, which allows the user to view the crimes for any time period on the map. A bar graph above the map also visualizes the number of crimes by day to provide an overview of crime rates over the selected period of time.
