One of my recent projects required careful analysis of JJ2 battle levels and I used graphs to visualize gathered results. The graphs show paths, intersections, and the most important places in every level. I find them useful for my research but I also had the thought I could share them and let people guess what levels they depict. So this is the thread where you can finally test your level history knowledge and some of your cryptography skills because I don't provide a detailed legend. The image is rather big so I'll put it in a link:

Graphs

Here are some tips: all of the levels are relatively well-known battle levels; most of them are quite recent (think past-2009), but not all of them; edges represent paths while nodes generally represent intersections and major dead ends; directions between linked nodes are relatively accurate, distances are not; colors mean the same thing for edges as they do for nodes and they're consistent between different graphs; shapes of nodes and edges mostly follow a complicated set of rules, with some exceptions where they're actually simple and consistent; neither of the levels is Battle1.

Nobody is expected to guess all of the graphs; if you think you got even a single one right, post about it and I'll answer whether your guess was correct. Bruteforce attempts will be ignored.

I realize I'm aiming for a niche audience with this puzzle and therefore may not gather much or any interest; if no one feels like guessing, I'll just wait for a few days and release answers as some people may find the graphs useful for whatever reason once they know what levels they relate to.
