Non-fiction comics, also known as graphic non-fiction, factual comics or documentary comics, is a genre of comic books and graphic novels that focuses on real-world events, people and places. Some popular synonyms for the term include non-fiction graphic novels, graphic memoirs, visual journalism, comic journalism and true stories in comics. These works vary in subject matter, from biographies and memoirs to historical accounts, scientific reports and social commentary. Non-fiction comics have gained popularity in recent years for their ability to present complex information in a visually engaging and accessible format, making them an attractive alternative to traditional text-heavy non-fiction books.
