Thematic maps are designed to display data in a variety of ways. These maps are used to display a particular specific theme within a specific geographic area. The data can be weather forecasts, election results, poverty, soil types, and the spread of a virus. The map above is a dot density map showing concentrated areas of density throughout Texas. The dots are a nonproportional point symbols where one dot equals one-hundred persons. This map shows an accurate depiction of population density since the data is not areal averaged and then displayed.
