Venn/Euler Diagrams

There's a real lack of reusable venn/euler diagram libraries. It would be awesome if this library added it.

Have you tried https://github.com/benfred/venn.js ?

Yes and it’s why I made this discussion 😅.

The author appears no longer active on GitHub and all of their libraries including Venn.js are unmaintained. The fork of Venn.js also seems to have become unmaintained. There’s a discussion here: benfred/fmin#16

I think it would be a great feature for Observable to have!

Thanks. I'm also using fmin in several projects.

The library might not have been updated for a long time, but it's still working very well as is:

Only caveat is that it's loading its own copy of d3 in a rather older version.

It would be interesting to couple it with Plot somehow — probably by returning the circles as geometries and using Plot.geo to draw them.
