Cleaning up the pie
The pie chart you made in the last plot is good, but it's a little cluttered. Let's clean it up using the ggplot function theme_void() along with giving it a meaningful title with ggtitle(...).
The disease_counts summarized data frame from the last exercise is already loaded for you.
