Network ConstructionConnection thickness—number of co-occurrences
Circle area—number of references to the entity in the text
Detecting ClustersBlue: “detective” (Robert, Sophie, police, Paris)
Orange: “mystic” (Leigh, Grail, Bible, Britain)
Green: “conspiracy” (Silas, Teacher, Jesuits, Castel Gandolfo)
BetweennessLabel size—betweenness centrality (BC). The higher is BC—the more “central” is the character / place
Highest BC: Robert, Sophie, Leigh, Bishop Aringarosa, Holy Grail, Captain Fache, Silas, Jesus, Leonardo, Church, and Sauniere
