    Interface VegaLiteFilterPredicate

    The object form of a filter transform predicate.

    Vega-Lite accepts either a predicate object ({field, equal}) or a raw expression string; Altair emits the former for alt.FieldEqualPredicate(...) and the latter for alt.datum.f == v.

    interface VegaLiteFilterPredicate {
        field?: string;
        equal?: string | number | boolean;
    }
