# Direct neighbours of notes: what they link to (`out`) and what links to them (`in`,

`POST /datanotes/operations/graph_neighbors/` (operation `graph_neighbors`)

Direct neighbours of notes: what they link to (`out`) and what links to them (`in`,
backlinks), with counts per edge label. `direction`: out, in or both (default).

`from_nodes` selects the notes: `{"paths": [...]}` and/or `{"table": ..., "where": {...}}`.
Edges are labelled with their link column (`people`, `event`, …) or `link` for other links.
