The University of Minnesota has developed a poster displaying the pedigrees of a bunch of hop varieties. It is for sale here: https://shop-secure.extension.umn.edu/PublicationDetail.aspx?ID=2069
Yeah, nothing can be done about that. They have a website template, and that's all the room they give for a preview. There's a bigger image here.
Seriously, I'd consider buying it if I could see what it looks like. Who doesn't have a large blowup of a poster for sale? A university, I guess.
I've seen electrical schematics for an entire facility less chaotic than that poster. At least it warns you in the fine print how complicated it is.
