Bar plots: dynamite plots

In the video we saw many reasons why "dynamite plots" (bar plots with error bars) are not well suited for their intended purpose of depicting distributions. If you really want error bars on bar plots, you can of course get them, but you'll need to set the positions manually. A point geom will typically serve you much better.

Nonetheless, you should know how to handle these kinds of plots, so let's give it a try.
