What is the proportional map use for?

A proportional map is used to visually represent data in a way that accurately reflects the relative proportions of the variables being depicted. This type of map adjusts the size of geographic features, such as countries or regions, according to the value of the variable being represented (e.g., population, GDP). This allows for easier comparisons and insights into spatial relationships and distributions. Proportional maps are particularly useful in fields like geography, economics, and Demographics.
