This post from It’s Okay To Be Smart got under my skin. The pictures, generated from the digits of pi, are pretty. But they should not be called “visualizations” of pi, because they have nothing to do with pi! The page also shows the results of the same algorithm applied to e and the golden ratio. They look kind of the same. And they would look the same applied to random digits. Because they are visualizations of random digits, not visualizations of pi.
