I believe that you are talking about the work "Persepolis" written and designed by Marjane Satrapi. If that is the case, Satrapi uses a chronological framework to tell her story, showing how the Islamic revolution has interfered in her life from childhood to adulthood, as well as showing how her family has been affected over time. This type of structure is efficient for communicating with an audience interested in history and impacting revolutions on life and ordinary people. Regarding the style, we can see that Satrapi used a simpler style, without striking details, showing that the story was more adult and dealt with strong and not childish themes.
"Persepolis" is an autobiographical grafic novel, where the author shows the development of her life within the Islamic revolution in Iran.
