Why would a geographer decide to use a proportional symbol map over a dot density map?

Responses

A proportional symbol map would be better if the information being represented stayed consistent across similar locations and changed gradually over different distances.
A proportional symbol map would be better if the subject being studied had discrete units which could be represented individually.
A proportional symbol map would be better if the information being represented was quantitative data in the form of percentages.
A proportional symbol map would be better if the subject being studied had varying sizes and intensities.

A proportional symbol map would be better if the subject being studied had varying sizes and intensities. This is because a proportional symbol map uses differently sized symbols to represent different values or intensities of a variable. This is useful in situations where the variable being studied varies significantly in size or intensity across different locations. In contrast, a dot density map uses a uniform dot symbol to represent a specific quantity or value. It is more suitable when the subject being studied has discrete units that can be represented individually, or when the information being represented is quantitative data in the form of percentages.
