Unstandardized Choropleth Map
Total water use per day by state in the United States
Unstandardized Choropleth maps portray data without averaging within specified units. The data is presented as a total raw value

Star Plots
Radar or star plot of selected peak ratios from gas chromatographic analysis of oil samples.
The star plot is a method of displaying multivariate data. Each star represents a single observation. Typically, star plots are generated in a multi-plot format with many stars on each page and each star representing one observation. Star plots are used to examine the relative values for a single data point and to locate similar points or dissimilar points.

Correlation Matrix
Pearson Correlation Coefficients / Significance / Number of Observations
The correlation matrix computes the correlation coefficients of the columns of a matrix. That is, row i and column j of the correlation matrix is the correlation between column i and column j of the original matrix. The diagonal elements of the correlation matrix will be 1 since they are the correlation of a column with itself. The correlation matrix is also symmetric since the correlation of column i with column j is the same as the correlation of column j with column i.
