A similarity matrix is a graphic with a matrix of scores used to show the similarities between data points. These maps are used to find clusters of data points and in aligning sequences of DNA.  The map above is a similarity matrix that is aligning a sequence of DNA.

A black and white Arial photo is exactly what the name says it is, an Arial picture in black and white.  These pictures are usually taken from a plane or a satellite and are used to view the roads, vegetation, and other topographical features in a different fashion. This map above is a black and white arial photo of an interstate in Baltimore.

A continuously variable proportional circle map is a map that uses circles to show various quantities of some phenomenon.  What makes it continuously variable is that there is no set range of sizes for the circle.  In these maps each numerical value has a corresponding circle size.  The map above shows the aggravated assault arrests by state through the use of circle size to show quantity.  Its easy to see that California has the highest number of arrests.

A star plot also know as a spider chart is a graphic used to show a bunch of information about sets of data.  These plots are used to show comparisons of two or more variables and the simultaneous outcomes.  The plot above is a star chart that compares the allocated budget of a company with the actual sales.  From the map one can see where the company allocated too much money and where the company didn't allocate enough money.

A stem and leaf plot is similar to a histogram in that it shows the distribution of a qualitative data set in a graphical format. This map type shows data broken down over intervals. the map above shows quiz scores for a class broken down in ten percent intervals.  The stem number is just an interval which the leaf is attached to.  For example the stem of '4' and its corresponding leaves show the numbers 40 and 49.

Box Plot

A Box plot is a graphic that shows data groups through quartiles that show percentile. Each box has lines called whiskers that extend out from the box to show the minimum and maximum observation. Sometimes outliers of the data will shown by plotting dots outside of the whiskers.  This map is showing Box plots of the various car cylinder makes and their correlated miles per gallon. Its clear to see that the more the cylinders, the lower the miles per gallon.

A histogram is a graphic that shows the statistical distribution of a set of data.  These maps are usually used to show a frequency of some variable across intervals. The map above shows the frequency of participating in sports or exercise across the different age intervals.  This histogram clearly shows that as age increases, participating in sports or exercise decreases.
