Yes, read the classic 'book' Understanding Comics, which is itself a comic/graphic novel about theories and practice behind creating graphic novels and telling stories with the medium.

As plain text it would be very dull and difficult to get the main points, but as a graphic novel it directly demonstrates how and why things work in the graphic medium.

It's really an incredible book that should be read by anyone doing creative things. https://scottmccloud.com/2-print/1-uc/
