Here's a very rough interactive on more recently published 7-way and 11-way venn: https://observablehq.com/@thadk/venn (with clean-ish svg, cites)

This fork shows an older version with all the shapes turned on and filled with original colors: https://observablehq.com/d/4a5120e490fa9da4

Santiago Ortiz's venn was from 2013 (via archive.org) . I had forgotten I'd seen that, thanks for sharing.
