The songs repeat the names of watering holes and other landmarks that let the singer follow this mental map while helping put the landscapes influence on their culture into perspective.

Is a graphical representation technique to compare all data in a multivariate data set. Is useful in measuring performance such as that of a car in the above image or the effectiveness of a project in different areas.

Correlation Matrix

A correlation matrix shows the statistical relationships between two sets of data that contain two variables each. Can be useful in looking at long term complex environmental trends such as wind speed/direction and changes in temperature/atmospheric pressure change for example.

Similarity Matrix

A similarity matrix graphically visualizes the similarity between two data points. The above graph is a comparison of notes in a popular rock song, it details the common repetitions heard throughout the music.

Stem and Leaf Plots

Stem and leaf plots are a way to display quantitative data graphically, it is similar to a histogram in that you can see the distribution of the data. This plot shows the infant mortality rate for Africa, the number on the left represents say 1000 so 9=9,000 and the numbers on the left equal 100 so the 2=200, therefore the number represents 9,0200 deaths.

Box and whisker plots use several different qualifiers such as mean and minimum value and present them graphically. This plot shows car gas mileage in six countries.
