The oval line is interrupted for a Braille capital letter: will that convey
to the blind reader that this line encompasses something called 'B' or 'C'
that's different from things outside?
Will the oval even be recognized for
an oval? The intersections don't make that any easier.
The ellipses will just be curved lines, and there appear to
be some numbers in the drawing. I think
sensible editing can make a
drawing like this a lot more meaningful: by hatching the sets in
different patterns, explaining these patterns in a key and stating 'Venn-
