Dot Distribution Map

This map above is a Dot Distribution Map and displays the numerous amounts of Walmart's throughout the United State and how it is turning into a virus. Dot Distribution Maps are useful to help show populations and portray quantitative data as a dot which represents a number of a phenomenon found within the boundary of a geographic area. The pattern of these dots shows the general locations where the phenomenon was most likely to happen. The pattern and number of these dots shows its density. As you can see from this map Walmart has expanded rapidly in the eastern part of the United States and is starting to build many of its stores in western USA. You can see that the dots are more dense in the south eastern part of the United States which shows the viewer that Walmart feels like most of there customers live in this region.
