In August I reported about 2D depiction of (CX)SMILES in Wikidata via linkouts (going back to 2017). Based on a script by Magnus Manske, I wrote a Wikidata gadget that uses the same CDK Depict (VHP4Safety mirror) to depict the 2D structure in Wikidata itself:

Depicting of part of a Wikidata page with 2D structures of a canonical SMILES and matching CXSMILES.

Note the depiction of the undefined (CIP) stereochemistry on two atoms. Thanks to Adriano and John for working that out.

More about CXSMILES in Wikidata in this Dagstuhl meeting results write up.
