A graphic novel is a book that tells a story through a combination of illustrations and text, similar to a comic book but typically longer and more complex. They often explore a wide range of genres, including fantasy, science fiction, and memoir, making them appealing to various audiences. Graphic novels use sequential art to convey narratives, with panels that guide readers through the story. This format allows for rich visual storytelling, where the artwork enhances the text, creating a unique reading experience. Popular examples include Maus by Art Spiegelman and Persepolis by Marjane Satrapi.
