In exploring the R ecosystem, I find myself exposed to lots of different ways of doing things, along with a real diversity of opinion on how to best present data. I’m working on studying up on that but for now, I’m satisfied giving lots of different things a try.

> library(ggExtra)
> p <- ggplot(diamonds, aes(carat,price)) + geom_point() + theme_classic()
> ggExtra::ggMarginal(p, type="histogram")
