Are we taking visual novel or the "light novel" as they are called in Japan where every few pages there might be splash art or a graphic novel which is a comic but bigger than the average issue?
The manga that someone else brought up: each of those chapters often show up in magazines in Japan and then we get the completed eight or so chapter books which could be called a graphic novel here in America/not Japan.
And then of course you have the webtoon and strips... All sorts of stuff.
How long is your comic/ideas? That will determine which format you'll want to choose.
Oh!! And motion books.
