Choropleth Map: A choropleth map uses different shades or colors within predefined areas (such as countries or regions) to represent statistical data. This technique helps visualize migration trends across geographical boundaries.
Dot Density Map: A dot density map represents individual data points (dots) on a map. Each dot represents a certain number of people or events in a specific location, providing insights into population distribution related to migration.
Flow Map: A flow map uses lines or arrows of varying thicknesses to represent movement between locations. This technique visualizes the volume and directionality of migration flows between countries or regions.
