Star Plots


A star plot is a multi-data representation of information. It uses various points to display the information within the plot. It uses spokes (lines) to connect the points within it. The data length of a spoke is proportional to the magnitude of the variable for the data point relative to the maximum magnitude of the variable across all data points. The above map is an example of a star plot, showing the crime rates within certain cities. It does not show the data used to mark each point but it shows how each point is different than other cities and how variables affect the image. The points given in each give the appearance of the star giving the name a star plot.
