[Scatter Plot with Shapes and Colors]

This scatter plot modifies the results of measuring the petal length, petal width, and sepal length for the flowers of three species of irises by:

using a DATA step to add a color variable and a shape variable to the data set
using shapes to distinguish iris species
using colors to distinguish iris species
using a Note statement to simulate a legend
