Problem

I'm always frustrated when I have to manually create Venn diagrams of more than 4 intersecting circles. It might sound trivial but arranging complex Venn diagrams in a legible manner is annoying and hard with most of the standard diagraming tools I've used.

Request

This was already brought up many years ago in #200 but Venn diagram in syntax in Mermaid would be great.

Venn Diagrams are basically just a visualization of set theory. So the syntax would just have to implement basic set operations:

Unions
Intersections
Compliments
Differences

Potential Syntax

Something like the following could be a good syntax:

vennDiagram
  set A
  set B
  set C

  intersect A B
  union B C
  relativeComplement A C

I know everyone is busy. I am just wondering what the general interest is from the community on prioritizing this versus other new diagram formats.

It would be useful, for sure. There have been multiple times when I looked to see if the gods had finally conspired to make Venn diagrams in mermaid a thing…

that being said is venn more useful than….. That, idk

Yup, I agree. I think a useful strategy here would be to ask anyone who wants it to 👍 the issue. If it's got enough community interest. I'd be happy to look at thinking it through more thoroughly in 2022 (among the million other things I gotta do 😂 )

I would love venn diagrams :) I'd be interested in helping when I start having more free time
