A flow map is a map that aims to show the movement of objects from one location to another.

Dot Distribution map

This map is an example of a dot distribution map. It is a map of Ohio that shows how many military families are scattered across the state, some living many hours away from the closest base. I picked this map because I have some very close friends in the military and they are scattered all over the US and this map of Ohio kind of gives you a little picture of how far apart some families are placed (or distributed) from others. http://operationmilitarykids.ohio4h.org/resources/images/dotMap.gif
