The is a criminal activity map from the Boulder, CO PD. In my opinon this is an excellent map. It follows all 20 Tufteisms and 6 Commandments put forth by Krygier.
This is a criminal activity map from San Francisco PD. The map uses terrible color combinations and bad text ratios making the map difficult to read. Also, Commandment 1: Map Substantial Information is not followed. You have to study the map too long to figure out what information is being conveyed.
