In graph theory, the crossing number of a graph G is the lowest number of edge crossings achievable in a plane drawing of G; a graph is planar exactly when its crossing number is zero. Determining the crossing number matters in graph drawing, since studies of how people read diagrams have shown that drawings with fewer crossings are easier to understand.

Is Kind Of Object
Entity-backed identity for the object-kind enum value this mathematical object already carries, resolved to a mathematics concept by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The object-kind fact itself stays on the object unchanged.
