Dot density map
Dot map; point density map; dot distribution map
A map with dots scattered to show the concentration of something in different areas. It's ideal for seeing how things are distributed over a geographical region, and can reveal patterns when the points cluster on the map.
Adjust dot density for clarity, e.g. one-to-one (one point represents a single count or object) or one-to-many (one point represents a particular unit, such as 1 point = 10 units). And consider using different dot sizes or colours to represent different categories. Don't use if your data isn't evenly distributed geographically or the density is too high to visualise clearly.
