Citing an ontology you rendered

Every diagram carries a Cite button when its source declares an owl:Ontology header. It reads the license, version, version IRI and creators straight out of that header and generates a BibTeX entry for the ontology — not for OntoInk — so a reader can cite what they are looking at without leaving the page. The button is hidden when the graph has no ontology declaration, which is itself a useful signal: an ontology published without header metadata cannot be cited properly by anyone.
