Box Plot

http://www.statmethods.net/graphs/boxplot.html
A Box plot is a graphic that shows data groups through quartiles that show percentile. Each box has lines called whiskers that extend out from the box to show the minimum and maximum observation. Sometimes outliers of the data will shown by plotting dots outside of the whiskers.  This map is showing Box plots of the various car cylinder makes and their correlated miles per gallon. Its clear to see that the more the cylinders, the lower the miles per gallon.
