-Range of data on one axis, frequency on the other.

-Each dots represnts one bit of info. More dots in one particular category means more frequently the event has occured.

Dot Maps:

-Show distribution and quantity using identical symbols.

-Use identical dots to show how something is distributed across an area.

-Use the key to find out what quantity each dot represents.
