Orkut Group Memberships
Orkut network, a network of the Koblenz Network Collection (KONECT) (User–group memberships). KONECT's file for it has the header `% bip unweighted`, i.e. a bipartite network with weights marked `unweighted`. This copy holds 327,037,487 edges between 2,783,196 user nodes and 8,730,857 group nodes.

Analytics
The full graph has 11,514,053 nodes; this view shows the 1,000-node sample the pipeline drew for display. Node size is centrality, colour is community.
Computed over the full corpus. Degree assortativity: exact — networkx's degree assortativity (Pearson correlation of the degrees at the two ends of every edge; directed: out-degree of the source against in-degree of the target), computed with DuckDB Bridge bottleneck count: exact — biconnected components of the undirected graph (NetworKit) Connected components: exact — connected components (NetworKit) Density: exact Reciprocity rate: exact (DuckDB) Top 10 centrality hubs: exact — full degree count (DuckDB)
