What is a dot map map?
A dot distribution map (or a dot density map or simply a dot map) is a type of thematic map that uses a point symbol to visualize the geographic distribution of a large number of related phenomena.
How do you make a dot map?

What are dot symbols on maps and what can they signify?
Dot distribution maps (or dot-density maps) depict a quantity for a given area by filling it in with small dots. Because each dot represents a quantity, you can expect that quantity every time you see that dot on the map.
What is Dot and sphere map?

What is the difference between a dot map and a choropleth map?
The choropleth map seen below of San Bernardino county population density uses random dots in this manner. Dot density maps, on the other hand, show the geographic density distribution of a phenomenon by placing dots representing a certain quantity of the phenomenon where they are most likely to occur.
What is dot map answer in one sentence?

What are the disadvantages of a dot distribution map?
Disadvantages
- Clustering may make it impossible to plot and interpret.
- Large numbers of dots difficult to count and calculate actual figures.
- Areas with no dots may give a false sense of emptiness.
- The size of the dot has to be carefully selected to show the distribution at it’s most clear.
