This chart shows (as best I could manage with the information I had) the connections in the LIWEU (literary-inspired webseries extended universe).
A guide to the lines: Shows connected with solid lines mention each other as real people in video canon. Shows connected with dotted lines have characters who interact through transmedia, including video descriptions. Dashed line connections are for Inseparables in All For One, since those are really their own category. And the tiniest dotted lines are for shows that are fictional in each other’s universes. There are a lot more of those, but if I added all of them, this chart would cease to make any sort of sense.
I only used arrows when the shows are clearly in a weird situation with each other (mutually fictional or just super not on the same page).
A huge thank you to everyone who helped with this. I’m not going to tag you all because I WILL forget someone, but you’re all amazing humans. If I left anything out, please let me know, and I’ll make an updated version!
