What you see is called a Venn diagram, a data visualization process invented by a guy named John Venn. It’s a simple way of picturing relationships between different groups of things or people.
In this diagram, overlapping parts indicate things the subjects in the circles (prostitutes, doctors, TSA agents) have in common.
A little humor for you…and surprisingly accurate. I fear your comments. Not.
By the way, what Americans call “junk” is called “family jewels” in Europe. Go figure…
