A flow map is a type of map used to show the movement of people, goods, or ideas from one location to another. It is usually represented by arrows or lines that connect different locations and indicate the direction and volume of the flow. Flow maps can be used to visualize transportation patterns, migration routes, trade networks, or any other type of movement between places. They are often used in geography, economics, and urban planning to analyze and understand the spatial distribution of activities and resources.
