Symbology is the use of symbols to represent the features and attributes of a map layer. For example, in a layer of cities, black circles might symbolize the cities. The size of the circles might be varied to symbolize each city's population. Symbols are defined by visual properties such as shape, size, color, spacing, and (in 3D) perspective height.
