This is cool.<p>I'll mention an alternative way to visualize Venn diagrams are UpSet Plots.<p>[1]: <a href="https://en.wikipedia.org/wiki/UpSet_plot" rel="nofollow">https://en.wikipedia.org/wiki/UpSet_plot</a>

Ah, I've made interactive Venn diagrams too! Such a niche topic. Here's a fun example of a 5-venn (give it a few seconds):<p><a href="https://editor.p5js.org/jwong/sketches/vC2x-M_QU" rel="nofollow">https://editor.p5js.org/jwong/sketches/vC2x-M_QU</a><p>I was investigating visual aids for math tutoring. Interactivity took a bit of work. Here's some alternative Venn implementations: <a href="https://wonger.dev/posts/behind-venn#prior-art" rel="nofollow">https://wonger.dev/posts/behind-venn#prior-art</a>
The 5-set Venn diagram looks beautiful (and is apparently by Branko Grünbaum), but is a similar symmetric 4-set Venn diagram also possible? Can't find any such example on the internet<p>EDIT: apparently not, from Wikipedia: "David Wilson Henderson showed, in 1963, that the existence of an n-Venn diagram with n-fold rotational symmetry implied that n was a prime number."
I've had an inkling at various times to make a widget or app or something for players of Diplomacy [0] that uses this visualization to make it easier to see activity in all of your conversations at a glance / select who to talk to. It always ends up being more of a 'fun' idea than something that would actually be useful, though, because the 6-set Venn diagram is so much more difficult to visually parse than just a list of countries in a "To" line.<p>[0] when played with "white press", which is where players can send messages to another player / to multiple other players, and the source of the message is authenticated. This is in contrast to "gray press" where the source is / can be anonymous instead of authenticated and "black press" where the source can be spoofed.
In case you need a quick Euler diagram (Venn and Euler are often mixed up), I recently found: <a href="https://eulerr.co/" rel="nofollow">https://eulerr.co/</a>
This would almost certainly be more difficult, but I'd love if the diagram's relative sizes (optionally) accounted for the size of the sets' data – e.g. if set A and B have 2 items each with zero overlap, it would show two circles of equal size, completely apart from one another
Wow, that 6-set visualization feels more asymmetric than 2,3,4,5. Is there an upper bound to the number of sets you can visualize in 2D, and how about 3D?
