Function lcc

python/graphscope/analytical/app/clustering.py:60–85

Local clustering coefficient of a node in a Graph is the fraction of pairs of the node’s neighbors that are adjacent to each other. Args: graph (:class:`graphscope.Graph`): A simple graph. Returns: :class:`graphscope.framework.context.VertexDataContextDAGNode`:
