Overlapping bar plots
You can customize bar plots further by adjusting the dodging so that your bars partially overlap each other. Instead of using position = "dodge", you're going to use position_dodge(), like you did with position_jitter() in the the previous exercises. Here, you'll save this as an object, posn_d, so that you can easily reuse it.
Remember, the reason you want to use position_dodge() (and position_jitter()) is to specify how much dodging (or jittering) you want.
For this example, you'll use the mtcars dataset.
