 Now, let's plot those occurrences on a world map. `{ggplot2}` and it's built-in function `map_data()` make this a breeze. Note that we use `alpha = 0.75` in case there are multiple occurrences in the same place. That way, the darker the fill color, the more occurrences in that geographic location.
