3. Population Pyramid

*Green = male population
**Gray = female population


I constructed this pyramid myself using raw data taken from the U.S. Census Bureau. Not only is this graph classified as Geovisualization, but more specifically it is a population pyramid AND a multivariate map. This graph reflects a "young" population, high fertility, and fast population growth. Maps such as these are often used in demographic profiles.

2. Isobars

 

This is a type of contour map that specifically shows information about air pressure and are often used by meteorologists to visualize weather patterns. The areas at which the isobars are closest together indicates high wind speed in those areas.

1. Mental Map

This is a map of the world that is clearly not accurate, however this is how the earth is perceived by the one that drew it. Thus indicating that the mapper knows very little about the geography of Africa and North America due to the lack of detail of those two continents. This planimetric map also illustrates critical cartography.
