If I had to draw circles to visualize SQL Joins, I would… cheat and use this…

IntroductionThis is just a simple article visually explaining SQL JOINs.BackgroundI'm a pretty visual person. Things seem to make more sense as a picture. I looked all over the Internet for a good graphical representation of SQL JOINs, but I couldn't find any to my liking. Some had good diagrams but lacked completeness (they didn't have all the possible JOINs), and some were just plain terrible.
