Let's flip some axes

First, we can practice rotating a plot. Provided is code that makes a bar plot of the number of cases of pertussis in the Americas region (AMR) in 1980. You will notice it's almost unreadable.

First, to help see patterns that may be in the data, reorder() the columns in descending order of cases.

Next, let's coord_flip() the axes to make it possible to read the country names.
