A reference article on Map Projections contains the following figure:

I think the images are created using Geocart, listed in Additional Resources section. I'm interested in trying to create visualizations like this--particularly the areal distortion and angular distortion visualizations--using open source tools. Either desktop GIS or code (Python, R, etc.) would be helpful.

    You could use the coordinate system and open source GIS tags together to come up with some candidates to test. Asking the community to come up with a list of candidates for you is what makes this too broad. Once you are testing a candidate and get stuck you will have a question suitable for focused Q&A. – PolyGeo Apr 11 '19 at 20:01
