Dan Kalikows Favorite Graph

Dan Kalikow describes his Favorite Graph in five parts, Part 1/5, My Favorite Graph: at the Equator.

"About 30 or 40 years back, I saw this graph in 'Sky & Telescope' magazine (see link at [1] below). I don't recall its author. I loved it and hung it on my office wall. It turned up again behind a bookcase a couple months ago, and I was so glad to renew acquaintances with it. For me, it has remained simply the most beautiful, the most chock-full of information graph ever, and that includes Minard's stunning multidimensional map/graph of Napoleon's March to Russia)"
