[edit] Who were they named after?

Who were Johnston diagrams named after? Was it the British logician William Ernest Johnson? Note the different spelling. See Scientific phenomena named after people. DFH 12:36, 7 August 2006 (UTC)

If you click on the logic tutorial link it is credited to Russell Johnston.

Which logic tutorial link?  --Lambiam 20:07, 23 January 2008 (UTC)

Is the only difference with Venn diagrams that the overlap of the circles represents A∧B instead of A∩B?  --Lambiam 21:37, 23 January 2008 (UTC)
