Star Plots


Star plots are a useful way to display multivariate observations with an arbitrary number of variables. Each observation is represented as a star-shaped figure with one ray for each variable. For a given observation, the length of each ray is made proportional to the size of that variable. This particular star plot is of automobile data. Each star represents one car model; each ray in the star is proportional to one variable.
