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.

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.

Cartogram

Cartograms are maps that are distorted so that the information represented demonstrates the point that is being made.

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.

DRG

A digital raster graphic map (DRG) is a type of topographical USGS (United States geographical survey). This DRG map is from the Texas Comission of Environmental Quality.

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.

Windrose

A windrose is a graph to show wind speed and direction and is typically circluar. I provided two different types of windroses to show how different they can look.

Histogram

A histogram is a statistical graph or map portrayed graphically with bars that can be shown horizontally or vertically. This particular graph is of the number of smokers female and male in 1992.

Isohyet

An isohyet is a type of contour or topographical map showing the amount of rainfall, usually by inches. This map was taken from the University of Texas and shows the amount of rainfall in a given amount of time.

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.
