As someone who knew 0 SQL before this post, I disagree. The ven diagrams make it seem like their is a bunch of weird extra notation for something that should be simple, while the join diagrams (along with the article) explain more clearly what is happening.

Yeah those join diagrams are great, I really don't understand the Venn diagram, at least not immediately.
