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 except located weighted equally and parallel edges counted separately; distinct is the number of different neighbours. 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 moved, developed, spawned, founded and became edges only, the lineage proper. Community hubs and the located edges are excluded from both calculations because every node is located in a hub by construction. High degree at an agency or a plan means many nodes on the map pass through it, not that it is important beyond the map.

Moves and capital only

Restricting the graph to the moves and capital relations changes the ranking: South Miami-Dade Busway, Lennar, Waterstone, Florida Department of Transportation District Six and South Dade TransitWay are the highest betweenness nodes in this version of the dataset, and the developers active on two or more named projects (David Blumberg and Miracle Development Corporation, Lennar, Adrian Homes, Electra America, Atlantic Pacific Companies and Housing Trust Group) carry the bridges between projects. 11 of the 41 developers on the map have a documented role on two or more named projects.
