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.

Unstandardized Chloropleth Map




This is an example of an unstandardized chloropleth map. As you can see, there is no specific ranking or ordering in the separations of minorities/race. It just simply shows the different types in different regions.

Bilateral Graph



A bilateral graph shows two related variables and the points at which they overlap. In this case, The United States Treasury Department looked at jobs versus unemployment rates over the time-span of January 2003 to November 2005.

Index Value Plot



This is an image of an index value plot. It is has several different dimensions to show differences and is plotted on a line graph.

Scatter Plot



This is an image of a scatter plot used by the United States Army. It plots the numbers of SATs versus the Beta test. Scatter plots are similar to line graphs, but can show up to four dimensions rather than just one.

Population Profile/Pyramid



Population profiles/pyramids show trends in statistical information regarding population over a number of years. This population profile shows the number of people that have AIDS according to gender and age.

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



This is an image of a parallel coordinate graph. They are used to plot large amounts of data. In this one, each variable corresponds with an axis and different colors are used to emphasize the information.

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.

DEM


A digitial elevation model (DEM) is used to show terrain and elevations among at certain ground positions and regularly spaced intervals. They are digital cartographic data in raster form. This image is of Crater Lake National Forest.

LIDAR

LIDAR stands for light detection and ranging technique. It is also known as 3-D laser scanning. This is a LIDAR image collected after a 2007 lanslide.

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.

Pie charts are an easy way to graph and visually comprehend information. This is a pie chart of different materials/items found in recycling bins.

Stem and Leaf Plot


Stem and leaf plots are a way to analyze data by creating a number graph that proves a certain set of data. They use numbers to produce values.

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.

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.
