FieldKind

FieldKind = "nominal" | "ordinal" | "quantitative" | "temporal" | "cyclic" | "geometry" | "identifier"

Defined in: packages/model-dataset/src/frame/field.ts:11

A field’s measurement scale — what operations on its values are meaningful, and therefore which visual channels it may drive.

This is the type system a renderer reasons with: it never inspects a cell to decide how to draw a field.
