Syntax tree (linguistics)

Native constituency / parse trees for linguistics and NLP teaching. Accepts both Penn Treebank parenthesised notation `(S (NP (DT The) (NN cat)) (VP (V sat)))` and a 2-space indented form. Non-terminals render bold; leaf terminals render italic in a classic serif face. Auto-laid-out so each node sits centred over its children.
