Euler

Draws only the regions that have members. If nothing belongs to both sets, the circles do not touch. If one set sits wholly inside another, it is drawn inside. The shape of the picture is itself a claim, so an Euler says more than a Venn and can be wrong in ways a Venn cannot.

Example

Best when the structure of the overlap is the finding and you can vouch for which regions are empty.
