RxClass Get Class Hierarchy
Traverse the drug-class hierarchy (ancestor chain / class tree) for a class ID in NLM RxClass via classGraph. Returns the ordered parent chain from a leaf class up to the classification root, with all nodes (classId, className, classType) and edges (child isa parent), plus a precomputed 'ancestor_path' from the requested class to the root. Default source is ATC. No API key required. Example: classId 'N02BA' ('Salicylic acid and derivatives') -> N02BA <- N02B ('OTHER ANALGESICS AND ANTIPYRETICS'…
