• One can [[categorificaion

  categorify]] this to “[[surface diagram

  surface diagrams]]”, which are dual to commutative diagrams in [[3-category

  3-categories]] (including monoidal \und{bicategories}, and \und{braided monoidal categories}). See for instance \und{here}.

• Yet more generally, one can categorify string diagrams to diagrams that are dual to commutative diagrams in [[n-category

  $n$-categories]], which yields the notion of [[manifold diagram

  manifold $n$-diagrams]].
