Twitter users have some things to say about Wisconsin Gov. Scott Walker's 'Venn diagram'

Gov. Scott Walker signed lame-duck legislation today at a news conference in Green Bay. The legislation scales back the authority of Gov.-elect Tony Evers.

To explain the changes in the law, Walker brought along some visual aids, including one intended to look like a Venn diagram. You know how those charts work. It's two circles that overlap to demonstrate a relationship between two sets. The similarities go in the middle and the differences go in the outer circles. 

But Walker's didn't include any differences.

People took notice of that misuse of a Venn diagram and sounded off on social media.
