graph_clustering_coefficient — CONNGRAPH stats op

• Data kinds: conn_graph → measurement

• Call: import fullseye as fs; fs.ledger.graph_clustering_coefficient(W: 'Any') -> 'float' (to call the implementation directly, import conngraph; conngraph.graph_clustering_coefficient(W: 'Any') -> 'float'; from the registry, opsconngraph.get("graph_clustering_coefficient"))

Usage

Mean local clustering coefficient (binary graph with directions collapsed, Watts–Strogatz). Nodes with degree < 2 count as 0.

C_i = (A³)_ii / (k_i (k_i − 1)), where A is symmetric binary. 1 for a complete graph, 0 for a tree.

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.

• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
