Who carries the connections

The figures below are computed on this dataset and nothing else. Degree is the number of edges attached to a node, with every edge type (personnel, spawning, influence, label, festival, collaboration) weighted equally and parallel edges between the same pair counted separately; distinct is the number of different neighbors. Betweenness is the share of shortest paths between all other pairs of nodes that pass through the node, on the simple undirected graph; it rewards nodes that bridge otherwise separate parts of the map. Personnel betweenness repeats the calculation on the subgraph of member, founder, moved to, spawned, became, side project and produced edges only, which is the family tree proper. Active and inactive nodes are treated alike, ambiguous affiliations were resolved to the band's own statement, and city nodes are excluded. High degree at a festival or label means many bands on the map passed through it, not that it is important beyond the map.

Personnel network only

Restricting the graph to personnel relations changes the ranking: Heavy Metal Princess Academy is the highest betweenness node in this version of the dataset, while Destrose, Mary's Blood, Nemophila and several individual musicians (Fuki, Mari, Saki and Mari Hamada) carry the women's scene bridges. The connective people appear here where the full graph hides them behind labels and festivals.
