Xan Gregg (photo below) posted all of the color scales used in the National Climate Assessment Volumes 1 & 2 on Twitter. I thought these were quite interested and wanted to share them with you. I encourage you to visit Xan on Twitter. Here is his link: https://twitter.com/xangregg
I also encourage you to visit his website, Packed Bars.
Mr. Gregg created a website all about packed bar charts, including examples, application, and alternatives.
