A Correlation Matrix is a graph view of the correlation between two numeric values.  This example is showing us the correlation between different criminal justice aspects of other countries.

Similarity Matrix

A Similarity Matrix is a matirix of scores that shows the comon characteristics between two data points.  This comes in useful when comparing or contrasting similar sets of data on a graph.  The example we are shown here is comparing the output of multiple machines to see what they have incomon and what their differences are.

Star Plot

A Star Plot is a graphical method that is used for displaring various datums in a two dimensional way.  The center of the diagram has a central meeting point where the variables will radiate out from.

A Stem and Leaf Plot is a tool for displaying quantitative data in a graphical means.  This can make viewing for the reader much easier than having all the numbers thrown out to them.

Stem and lea plot

Boxes drawn either horizontal or vertical depicting graphical data are known as box plots.  This is a convient and effective manor of displaying relative information.  The example is comparing a machines ability to output energy.

Histogram

A Histogram is a a graphical representation of the distribution of data, shown as adjacent rectangles.  This example of sizes of fish could also be called a simple bar graph.

A Tiangular Plot is a plot that has three different data variables.  When using an equilateral triangle it makes it easy for the viewer to compare the three categories of data.  This particular example shows us a comparison of three ultramafic rocks found in this area.

Windrose

A Windrose, also known as a compass rose, is a figure on a map or chart that is used to display the orientation of the cardinal directions.  The windrose will usually point which way is North, and then the viewer can conclude which way the other directions are.

Climograph

A Climograph is a graph that shows the viwer the climate for a certain area.  This particular climograph uses a bar graph to show the climate for Honolulu, Hawaii.

Population Profile

A Population Profile is a graph that shows the viewer data about a particular population.  These are always used in the census, but can be used in smaller groupings as well.

Scatterplot

A Scatterplot is a diagram that uses coordinates to display data.  The coordinates consist of one value being on the X axis and another value being on the Y axis.  To read the data one would go to the point as follows; (X,Y).  The scatterplot here shows us how test scores compare to hours spent studying.

Index Value Plot

An Index Value Plot is a graph that makes the extremes stand out to the reader.  The extremes are shown by being on one side or the other of a relative line which is the "normal line" and considered to be an average.

Accumulative Line Graph

An Accumulative Line Graph is a graph that is used when the author wants the viewer to be aware of the most up-to-date total that is possible.  Every new point includes the value from the last point so that it is cummulative and incorporates all the data.  As the reader can see here, each day is incorporated in the next as the cumulative mileage never goes downward.

Bilateral Graph

A Bilateral Graph is a graph that compares two opposite sets of data.  It will show increases on one side of a zero line and decreases on the other.  This becomes a great tool to use when both negative and positive numbers need to be shown.

Range Graded Proportional Circle Map

A Range Graded Proportional Circle Map is a map that uses circles based on their size to correlate directly to the quantity for that data given in the symbol key. As we see from the example, the ppm of zinc in the surrounding area.

Continuously Variable Proportional Circle Map

A Continuously Variable Proportional Circle Map has a lot in common with a proportional circle map, actually it is a proportional circle map, it just has more data involved to convey more information.  The circles can also be in proportion to the data rather than in proportion to the area.

Digital Orthophoto Quarter Quads

Digital Orthophoto Quater Quads are digital aerial images produced by the USGS.  The example here is a map of Florida, digitally redone by the US Geological Survey.

Digital Elevation Model

A Digital Elevation Model is a three dimensional representation of a terrain's surface, digitally.  DEM's are often used for space models such as Earth, moons, or other planets, to show what their terrain looks like.  The example here shows us a digital elevation model of the terrain of Mt St Helens after the eruption in May of 1980.  You can see the entire top of the volcano was blown away from the blast.

Digital Line Graph

A Digital Line Graph map is another feature that is incorporated with a USGS map.  These lines are present to represent topographic information. 

Digital Line Graph

Digital Raster Graphic

A Digital Raster Graphic map is a map that is turned into a digital image after it is scanned.   The map usually includes the original border, as we can see from the example. (the blue line)  These scanned images are taken from USGS maps.
