Nominal Area Choropleth Map
This is an example of a nominal area choropleth map. There is an apparent constant unit measuring areas and percentiles of condo owners that are African American.

Similarity Matrix
Star Plot
Star plots contain a lot of information in that each star plot represents a single observation with a number of different variables per that observation. I have given an image of a star plot of an analysis of automobiles from the year 1979. As mentioned on the website, they can be looked at individually or as clusters.

Climograph
Climographs are used to show two different variables. It consists of a bar graph representing the amount of precipitation and a line graph for the temperature. In this particular graph, we are looking at the temperature and precipitation of Beunos Aires, Argentina over a year.

Parallel Coordinate Graph
Mental Maps
This is an example of a mental map. Mental maps can be anything from sophisticated and detailed, to just a little swirl on a page. This person chose to portray a map to get to school. As you can see there are sidewalks, houses, names of a few streets, and the location of the school.

Flow Chart
Flow maps are used to show movement of an object, person, or idea from one place to another. It is an algorithym or process used in designing or portraying information. Although somewhat silly, I added this flow chart of the Hokey Pokey. I thought it was funny to see among serious flow charts! However, it does show the process of movement.

DLG
Digital line graphs (DLG) are digital vector data representing cartographic information. They provide a wide variety of information and geographic features. This can include political or administrative boundaries, vegetation, transportation data, land survey systems, hudrography, etc.

Triangular Plot
Triangular plots are often used by scientists and engineers, but anyone can use them to show usually three variables (but can be more variables) of data graphically. This triangular plot is an analysis of votes in the UK. The different variables in this case, are the different parties in the upcoming election.

Proportional Circle Map
A proportional circle map is a point pattern map with circles rather than dots. The size of the circle relates to the measured variable. This proportional circle map shows the number of people in Europe that used the internet in the year 2004.

Correlation Matrix
A correlation matrix is a rectangular array of numbers that gives the correlations between all data sets. In this correlation matrix, the information shown is a heat map of tissues to tissue cancerous cells. The lines separate cancerous tissues, and the color spectrum goes from blue to white to red.

DOQQ
Digital orthoimagery quarter quadrangle is a computer generated image of an aerial photograph. They can be in black and white, natural color, or infrared. This DOQQ is an image of a portion of Washington, DC.

Dot Density/Distribution Map
http://cartophilia.com/blog/images/popdensity.jpg
Dot density maps are a type of point pattern map. It is a nonproportional point symbol that does not vary in size. One dot represents 10,000 people. This particular dot distribution map is used to show the populations in the United States in the year 2000.

yay i figured this out
I still have to post my first map. I'm just glad I figured this thing out :o)
