Mutually Exclusive Venn Diagrams

[42Willow]

Eg.

#cetz.canvas({
  import cetz.draw: *
  venn2(name:"venn")
  content("venn.a", [10])
  content("venn.b", [20])
  content("venn.ab", [0])
})

should not have an overlapping section in my opinion

Sets with empty intersections are not part of this package, because they are easy to draw with cetz. But I can see including them being useful.
