I have seen many “plots” of prime numbers that look really good. In addition to looking good, I sometimes _swear_ I see a pattern. It’s really frustrating, to see something on a graph which looks like it follows some pattern or algorithm[1], and to know that finding the mathematical definition of that pattern would would be revolutionary, world news. I can see why so many people get sucked into this problem.
