# Exploring Data in Three Dimensions

SAS/INSIGHT software provides rotating plots, surface plots, and contour plots for exploring data in three dimensions. A

*rotating plot* is a three-dimensional scatter plot, so it shows a graphic representation of the relationship among three interval variables. A

*surface plot* is a rotating plot with a surface that models a third variable as a function of two other variables. A

*contour plot* shows how the values of one variable may depend on the values of two other variables.
