Graph theory can help you understand the social landscape of the books in the series A Song of Ice and Fire by G. R. R. Martin. With the judicious use of Maple, you can ask yourself really pressing questions like

• Who is the most influential person in Westeros? How has their influence changed over the five books?
• How are Eddard Stark and Randyll Tarly connected?
• What do eigenvectors have to do with the battle for the Iron Throne, anyway?

This application uses data from the books. See A Game of Thrones and Graph Theory to ask these types of questions using data for the television series.
