Sometimes I get rather caught up in the various dross and droll of the geocoding and mapping subject (read: thrash) as it relates to analytics, and I forget that a good map does not have to reference actual geography to represent a theme of data... Seems like a "D'uh" moment. I must be getting old.
The data below comes from http://data.seattle.gov and this visual uses a simple police precinct image as the background.
The basic conclusion I can come to with this data is: overall, crime is quite a bit down year over year for 2008-2009. Nifty.
All Crime Data | Crime Decreases | Crime Increases
