How can I draw a rectangle around a Venn Diagram: A \cap B, A \cup B, etc? Thanks

[Stefan Kottwitz]

Hi,

perhaps show the code that you are using, and some of us could add the rectangle. For now, nobody knows how the diagram is actually made. I just assume it's done in TikZ. So one could use the fit library, or ad it manually.
