Congratulations on the book drop!
So I'm not sure if you read my piece or just wanted to drop a promotion, but I think you're misrepresenting my view here. I'm not advocating for "art for the sake of art" and I certainly don't think you should not know your audience.
My main point is that I don't think all of data viz is as simple as you're implying here, i.e. that a pretty chart probably won't "resonate" or that a chart from the Tufte school of thought automatically will.
