SPLOM Chart

SPLOM or scatter plot matrix is a technique invented by John Hartigan in 1975 used to determine correlation between a series of variables. These scatter plots are organized into a matrix to facilitaet data exploration. Here are some exaples with multiple configurations using the Fisher's Iris data set
