It's not often that you encounter a graph and you think, "Wow! My god, that is a spectacular graph!" I have such a graph for you, reader, and it just so happens to be about gonorrhea. I know what you're thinking, "she can really pick 'em, huh? Exceptional taste in data presentation."
Truly though, this graph is a wonderful piece of historical data, a beautiful 2-D chart that plainly illustrates a few of the major social and cultural forces that have occurred in the United States this past century. Namely, the Second World War, the emergence of the Baby Boomer generation and the sexual revolution. This is heavy-duty stuff, people!
