Oops, I don't know why I didn't see this issue before! (GH notifications are so weird sometimes.)

What would be the benefit of visualizing via ggplot2? (Mind you I'm coming at this as someone who uses ggplot2 all the time in every project.) I think it would add unnecessary processing overhead and base makes visualizing probability densities super easy and simple via the curve function.
