  "description": "One element in the definition form (v3-style JSON), as accepted by `cytoscape( { elements } )`, `cy.add()`, `cy.patch()` and each chunk of `cy.load()`, and as written by `ele.json()`. Describes cytoscape 4.0.0-unstable. The group is inferred from `data.source` and `data.target` when omitted; an explicit `group` must be 'nodes' or 'edges', and an explicit edge must name both endpoints. Keys the library does not read (v3's `classes` and `scratch`, `ele.json()`'s `removed`) are ignored, not refused, so the schema leaves the object open. What stays the library's job: unique ids, endpoints and parents that name existing nodes.",
