One thing I noticed about telling a story in a graphic format is that the author has control of the visualization of the story. When just reading a text, different people are going to envision the story in different ways. However, by having those pictures the author can portray the story in whatever way they like. Additionally, this graphic format allows authors to convey a deeper meaning of the story through the style they use. Through different styles, the author can evoke different emotions in the reader which provides another aspect of conveying information besides the text and pictures themselves. In Persepolis, for example, the black and white pictures along with the style contribute to the seriousness of the story.
