Unstandardized choropleth maps



The unstandardized choropleth map is like all other choropleth maps: it uses to color and shading to reflect the data of a variable throughout a geographical location. The unstandarized choropleth map represents a genre of choropleth maps that do not have a standardized system in place. This is because either there is no system required (as with nominal data) or a system is chosen to not use it despite numerical data being present. In the case of the map displayed here, there is no standardization required because the data is nominal as it relates to climate zones across Australia. Here we can see that the desert—hot and persistently dry—dominates the central areas of the continent while the far north is a savanna climate.
