Star Plot

http://math.yorku.ca/SCS/sugi/sugi16-paper.html
Star plots are used to plot data with several variables. All of the data had the origin in the middle, and the different variables each point in a different direction. The length of the line from the origin shows us the data. This star plot shows various automobile data like price, length, weight, trunk and miles per gallon for each car pictured. The result is a visual representation of the cars which you can relate to one another.

Similarity Matrix

This is a similarity matrix for different music. Similarity matrices are used to express data between two objects. This map shows the relationship between some different songs, giving higher scores to ones that are more similar--the most similar are shown in white, next in yellow, third in green and least similar are shown in blue.

Box Plot

This box plot compares efficiency of four different machines. Box plots show a summary of data by showing the minimum (bottom of the line), maximum (top of the line) and the 25th and 75th percentile of the data set shown in the box.

Stem and Leaf Plot

Stem and Leaf Plots show data organized into groups based on similar characteristics. This plot shows a mathematical sequence, with the numbers organized by groups of tens. This is useful for finding averages or similarities between data sets.

Triangular Plot

Triangle plots show the relationship between three variables on three axes. This plot shows the predicted impact of tsunami waves on three separate sites based on a scaled index.

Windrose

Windrose maps show the speed and direction of the wind over a certain period of time in a specified area. This map shows the wind speed was southerly in Springfield, MO most of the time between 1973 and 2006. 

Climograph

Climographs show the difference between rainfall and temperature over a certain period of time. This map shows the entire year's precipitation through a bar graph overlaid with a red line marking temperature. These maps are useful for depicting weather trends, droughts, and flood seasons.
