causalens

Define, manipulate, and serialize causal graph structures (DAG, CPDAG, MAG, PAG) using cai-causal-graph. Provides CausalGraph, Node, Edge, Skeleton classes with variable type support (CONTINUOUS, BINARY, MULTICLASS, ORDINAL). Use when user imports from cai_causal_graph, works with causal graphs, needs graph conversion (NetworkX, adjacency matrix, dict), or mentions DAG/CPDAG/PAG/MAG representations. Do NOT trigger for graph neural networks or knowledge graphs unrelated to causality.
