Data columns types affect plot types

The plot from the previous exercise wasn't really satisfying. Although cyl (the number of cylinders) is categorical, you probably noticed that it is classified as numeric in mtcars. This is really misleading because the representation in the plot doesn't match the actual data type. You'll have to explicitly tell ggplot2 that cyl is a categorical variable.
