Reduced views of companies connected by shared directors.
The full non-isolate company graph. This keeps the original view but removes companies with no shared-director edge.
Companies connected only when at least two directors appear on both boards.
A stricter version that breaks the giant graph into smaller, more interpretable islands.
Louvain communities inside the giant component, shown as capped islands of central companies.
Dense closed-end fund families that otherwise dominate the shared-director graph.
A shortest-path UMAP layout of the largest connected component.
Exploratory correlations between graph centrality features and later share-price movement.
Edges count distinct shared directors between companies.
