Also known as dot density maps, dot distribution maps use dot symbols to demonstrate what the map is representing.  Dot distribution maps are often used for population density but can be used many other ways.  In this map, the dots represent locations of meth labs in 2005 where 1 dot equals 5 labs.  As you can see, in this map, the majority of meth labs in 2005 are located in the middle of the United States.  It also leaves Albuquerque, New Mexico dotless, keeping Walter White discrete.
