Starplot

A Starplot allows the user to easily visualize and compare multiple variables across observations. Each observation is shown as a star shape, with each ray representing a variable. The variables are plotted on the radii, which represents different characteristics. The length of the ray is related to the size of the variable. The resulting shape of the starplot is then compared to the shape of other starplots formed from separate observations, which are easiest to compare when all of the variables have their scales aligned in the same direction, so that increasing and decreasing values represent the same measure. This starplot shows a number of variables relating to automobiles. Each starplot is a different car model. Each ray is a variable such as price, mpg, headroom, trunk space, etc.
