Actually, it's a near-perfect article from my point of view. I don't (regularly) work in tables, I'm not immersed in data visualization culture, and I wouldn't have thought twice about reading a simple "here is our product" page aimed only at people who already know what they're looking for. However, this article gave me some really interesting and valuable background material and then concluded with solid, crystal clear (even to me, who's never written python) examples. I actually came away thinking, "well, this look fun - I should spin up some toy project to play around with this and learn how to use it."
