The huge popularity of Graton's series is partly due to their extreme realism. Graton's works, particularly the Michel Vaillant series, are notable for featuring real-life people, drivers, teams, races, and places. Graton is widely recognized as a great automobile and motorsport drawer.^{[citation needed]} The several descriptions of places, circuits, and cars he gave in his series are highly well-documented, specific, and realistic. Graton used to take a lot of notes, illustrations, and photographs of the various automobile-related places he attended as an automobile-passionate. He was later assisted with this work by his son Philippe, who has a passion for photography.

Graton's passion for motorsport went back to his childhood. Later in his life, he attended numerous Formula One and other motorsport races, and was acknowledged by famous drivers. His series inspired some drivers to choose such a career.^{[citation needed]}
