1. How could you rescale the count dataset above to more clearly show the distribution of cut within color; or color within cut?
2. Use geom_tile() together with dplyr to explore how average flight delays vary by destination and month of the year. What makes the plot difficult to read? How could you improve it?
Why is it slightly better to use aes(X = color, color = cut) in the example above, rather than aes(X = cut, color = cut)?
