Exploring missing data with scatter plots

Missing values in a scatter plot in ggplot2 are removed by default, with a warning.

We can display missing values in a scatter plot, using geom_miss_point() - a special ggplot2 geom that shifts the missing values into the plot, displaying them 10% below the minimum of the variable.

Let's practice using this visualization with the oceanbuoys dataset.
