I thought "huh, some hospital link," but it appears to be a scam site, so be wary of clicking. (Good advice anyway, but I naively thought I could trust a link on HN.)

Which link did you follow, by the way? I clicked a few, and the link to https://www.edwardtufte.com/tufte/books_visex is broken, but none took me to your link.
