How to Visualize Crime by Location
The effectiveness of a good crime map owes a lot to the flexibility it provides users in filtering the visualization of crime by location, type of crime, date and time of day. The San Francisco Crimespotting map provides a great example of how you can give users control over the visualization of crime data.
The map uses colored map markers to show the location of different types of crime. You can filter the types of crime displayed by using the controls in the map sidebar. You can also mouse-over the individual crimes listed in the sidebar to view all those crimes highlighted on the map.
The 'date' and 'time of day' controls also allow you to filer the results shown on the map by any date range or for any period or combination of periods during the day.
