You're right that these data visualizations are more effective than the data presented in text form. I'm not a visual person--I as born almost blind so didn't see anything well until I got glasses at age 6--so the fact that I say this about your article is, I think, significant.

Hmm. I write a number of articles that are heavily dependent upon data. Here's an example still in draft mode: https://medium.com/bigger-picture/could-we-really-deport-11-million-undocumented-immigrants-087795a5ee43. Would you be interested in creating illustrations for some of my articles if I include obvious thank you notes in the articles?

I don't have a large following on Medium, but I do have a dedicated crowd of people who read what I write and would see my thank you notes to you.
