Karate Club (a) and Les Misérables (b) zone networks. The networks were transformed into the weighted directed networks of sub-zones and zones nested in overlaps. Each pair of nodes in this transformed network connected by a directed edge represents zones; the smaller node represents the sub-zone that is nested into the super-zone represented by the larger node. The size of each zone corresponds to the number of nodes in this zone, and the edge strength corresponds to the number of nodes of the sub-zone. Red nodes represent zones that have no super-zone, green ones zones without sub-zones. The yellow zones have both sub-zones and super-zones, and blue zones have neither sub-zones nor super-zones. In sub-figure a with Karate Club, there is a multi-ego zone (node 6+1) with two egos 6 and 7, one liaison 1 and three other nodes 5, 11, 17 (see also Fig. 2). Moreover, there are, e.g., two alternative zones with egos 9 or 31 (9 ALT or 31 ALT). The first one has one liaison, 34, one co-liaison, 33, and one other node, 31. The second one has the same liaison, 34; however, it has two co-liaisons, 9, 33, and no other node. Similarly, in sub-figure b, Enjolras’s zone has three other egos and one alternative Gavroche’s zone. If the zone has at least two edges directed to different zones, then it is contained in their overlap. While in Karate Club, there are no zones nested in overlaps, the Les Misérables network has, for instance, such zones for Cosette, Pontmercy, and Mabeuf
