The Deadliest Atlantic Hurricanes (until I think of something different)

I am creating a heat map and graph illustrating the top 5 deadliest hurricanes from 1900–present... I might include the hurricane's category.

The pink colors are a place holder for the moment but if I do keep "Deadliest" in the title I will change the colors to shades of orange or red.
