Overplotting 2: Aligned values

Let's take a look at another case where we should be aware of overplotting: Aligning values on a single axis.

This occurs when one axis is continuous and the other is categorical, which can be overcome with some form of jittering.

In the mtcars data set, fam and fcyl are categorical variants of cyl and am.
