This week's blog post features "raincloud plots", a relatively recent development in data visualization. Will the raincloud plot gradually replace the box plot? It just might! Check out the raincloud plot for the planets in our solar system at www.jasp-services.com/jasp-for-qua...

If you cannot sleep because you keep wondering why the two whiskers of a box plot can be of very different length (and why this is a Very Sensible Idea), then this blog post is for you! :-) Boxplots 101, plus planets: www.jasp-services.com/jasp-for-qua...
