Signature

edgeAttribute(name, valueOrFn, options = {}) {

options	AttributeWriteOptions	optional		Optional type, dimension, and indexing controls.

Array-like values are aligned to the active edge ordinal by default. Pass { indexBy: 'id' } when your values are keyed by stable edge id instead. For bulk streaming writes into existing typed arrays, use the explicit buffer API.
