A distribution map utilizes dots or other symbols to represent the presence, quantity, or value of a phenomenon or thing in a specific area. In a dot distribution map, the size of the dots is scaled in proportion to the intensity of the variable. Looking at this specific map about how many public libraries there are in the US, we can quickly see a clear depiction of what areas are clustered with more libraries. It is useful for researchers and analysts who can compare the northeast region versus the central west as it is evident that the northeast region of the United States have the most public funding.
