Of course nice / "proper" / usable Venn diagrams use only round(-ish) shapes so they are easy to decipher. If you stick to this limitation, you can visualize up to 3 sets in 2D (using circles), 4 sets in 3D (using spheres), then it gets tricky...

Ovals, arguably roundish, can do 4 sets well in 2D.

Right. I don't find that clear anymore. Seems more like a puzzle to me.

The 3D one works somewhat well if the spheres are translucent and animated.

I think this 6 set Venn Diagram is nice because I made it. :)

How did you make this? It is nice. Why does the red line have a heart-shaped bounce/curve in the open white space instead of just being round?

Type "Polar plot 6 curves of the form r = (1 + Sin[2^(k - 1) t]/2^(k - 1)) where k =1, 2, .., 6 and t=0 to 2 Pi each curve should be a different color" into ChatGPT5.

It has the nice properties that you can do any number of sets (in theory) and all the boundary intersections are either osculating or perpendicular.

Looks like sinusoids in polar coordinates

I wonder why when swipeing between the two sides of the disc it always appears convex from the currently viewed side, but flat when viewed edge on.

Anyone knows what could cause this?

I think it's to avoid having two sets of data points. I think the "view angle" affects the "convex amount" so that edge-view = flat and all other viewing angles "bump" the data points a little bit to give the "convex" look.

Please don’t actually use these 5,6,7-way Venn diagrams for anything practical, they’re virtually useless and communicate nothing.

Technically a Venn diagram's entire point is to visualize all possible set relations between N sets. Their "practical" use is explicitly visualizing this.

In popular terminology they are very often confused with Euler Diagrams [0] which represent meaningful relations in sets but not all possible. You shouldn't create Euler Diagrams this complex, but the raison d'etre of Venn diagrams is to visualize the complex nature of set relations.

There is always the complicated wires puzzle from "Keep Talking and Nobody Explodes". Where a 5 way Venn diagram encodes what action you need to take for a given state.

However you could make a good argument that having a complicated and confusing diagram is the point of that puzzle.

Agree, I think the linked Upset diagram is better.

Thanks, I was just about to do that!

Beautiful! I want to get this on a t-shirt!

The source has a distinct face-melting vibe. Judging from leftover variables, seems like part of the original plan was to make a 7-way Venn diagram of these broad disciplines: "ART INTERFACE SCIENCE LANGUAGE TECHNOLOGY HUMANISM NETWORKS".

The possible resulting combinations also seem to have remained in the code, going from tame concepts like "illustration" and "games", down to gems like "folksonomy", "hypernarrative", "facebook" (??)

Can this be configurable? Like 8..9..etc
