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
