the comments here https://news.ycombinator.com/item?id=45742907 have some discussion about projects that take a "focused algorithm for various different diagram types" approach vs graphviz's one size fits all approach. worth checking to see if any of them do venn diagrams.

Nice! I wonder if there's a mathematical theorem to describe the possible shapes for a 2-d venn diagram of N sets or if there's an N for which it is no longer possible (or maybe it's possible for all N!?). Probably an application of graph theory and Euler's formula to determine feasibility and then something else to figure out the shape constraints. Never thought about it, but an interesting idea.

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

I’m wondering what’s the proper way to draw Venn diagrams. I’ve seen that Graphviz has a “nice to have” mention about them, and there are a few simple JS libraries - mostly for two sets. Here’s also my own attempt using an LLM [1].
But maybe someone knows a more general or robust solution - or a better way to achieve this? In the future, I’d like to be able, for example, to find the intersection between two Venn diagrams of three sets each etc.
