From: A simple approach for quantifying node centrality in signed and directed social networks
Social network constructed by using data collected for class h in December 2005 (i.e. class h 0512 dataset). Girls and boys are represented by open circles and filled circles respectively. Thick lines are friend-nominating ties while thin lines are enemy-nominating ties. The size of the nodes reflects the feeling score of the students: larger the node size higher the feeling score
