Three Maps

Isarithmic Map: Isarithmic maps, also known as contour maps, depict smooth continuous phenomena such as precipitation. The map shown is an isarithmic map of the hydrogen ion concentration as pH from measurements during 1998. 

Chloropleth Map: A choropleth map is a thematic map in which areas are shaded or patterned inwhich shows to the measurement of the statistical variable being displayed on the map, such as population density or per-capita income.The choropleth map provides an easy way to visualize how a measurement varies across a geographic area or it shows the level of variability within a region. The map below is a chloropleth map of Kazakhstan's average temperature in july. 

Dot Density Map: A dot density map is as a map type that uses a dot symbol to show the presence of a feature or phenomenon. Dot maps rely on a visual scatter to show spatial pattern. The dot density map below is of the U.S. population in 2000.
