[PubQ] Anyone have any experience with publishing graphic novels? I'm curious about the process!

I'm an illustrator hoping to break into one or multiple areas of publishing, and graphic novels may be among them because they're, like...really, really cool? I just think they're neat! I have tons of them. The process of how they're actually made in traditional publishing is a little opaque, though. I know the basics, but beyond that is a mystery, and I'm both autistic and very curious so I HAVE to know. Any insight would be greatly appreciated! Thank you for reading :)
