Parallel Coordinate Graphs are able to show large amounts of variable statistics at once. Each color represents a different variable. A great example of this would be sports statistics. In baseball, each color would be a different hitter and each statistic, a different time at bat.

Thematic Maps are used to show specific information without distorting the given geographical location. The example above shows the time zones of the United States but thematic maps are not limited to this type of information. Choropleth, Isarithmic, and Dot maps are all examples of thematic map making.

Propaganda Maps are used through out history but are noticed mainly at times of war; this is when maps are used as a symbol of power. The image above is from the Japanese before the 1905 Russo-Japanese War, showing Russia as the “Black Octopus.

Doppler Radar is used to show the weather over a given area. We see Doppler radar images used daily in our local weather forecast as well as online programs. Doppler radar is also used in aircraft's and Police speed guns. For the well known weather map version, microwave radiation is released in waves from a Doppler radar station, allowing the station to, in turn, receive information for the image.

A Light Detection And Ranging map, otherwise known as a LIDAR, gives us the evelation or any given area using laser technology. Using short wavelentghs, LIDAR uses reflection to give us a 3D view of a location, making it easy to see any changes in the area.

The DEM shows a representation of a geographical locations terrain. Above is a pretty basic representation of the United States' land. DEM can also be referred to as digital terrain model (DTM). DEM shows a more naked version of the Earths elevation and texture, rather than the Digital Surface Model or DSM which includes roads and buildings.

A scatter plot is a graph that we become familiar with starting in early math classes. It is "designed" by plotting multivariate values. This particular scatter plot is a visual for the Pythagorean triple. Other scatter plots may be used to show basics such as how age effect the amount of "best friends" you have or even crime vs population.

This is an example of a star plot. I decided to use an older star plot example mainly because I think it is beautiful. A star plot shows us where constellations are located. This map breaks the nightly location of the stars up based on the northern and southern hemispheres.

This image is the perfect description of a mental map. Mental mapping is a basic and key form of cartography that we use on a daily basis. Mental Mapping is how was save information in our brain, giving us either memories when a location is mentioned or even getting ourselves somewhere based on "autopilot".
