Scatterplot matrices are a great way to roughly determine if you have a linear correlation between multiple variables.

For a set of data variables (dimensions) X_{1}, X_{2}, … , X_{k}, the scatter plot matrix shows all the pairwise scatter plots of the variables on a single view with multiple scatterplots in a matrix format.

This is the most basic scatter plot you can do, just calling the plot function.

See custom scatterplot matrix in graph #97 and graph #99 !
