    Interface VegaView

    Minimal subset of a Vega View that the adapter needs at runtime.

    The compiled view exposes processed datasets (post-transform / aggregate) via VegaView.data, which is the most accurate source for chart data extraction.

    VegaView.runAsync is used by the adapter to wait for the first render frame to complete, which guarantees the SVG element exists in the container before MAIDR tries to mount on it.

    interface VegaView {
        data: (name: string) => Record<string, unknown>[];
        container: () => HTMLElement | null;
        runAsync: () => Promise<VegaView>;
        scale: (name: string) => { domain: () => unknown[] } | undefined;
    }

    data: (name: string) => Record<string, unknown>[]
    container: () => HTMLElement | null
    runAsync: () => Promise<VegaView>
    scale: (name: string) => { domain: () => unknown[] } | undefined

    Look up a Vega scale by name (e.g. 'x', 'y', 'color').

    Returns undefined if the scale doesn't exist. The scale's domain() provides the rendered domain in the order Vega uses to lay out marks — used by the adapter to align data ordering with the SVG DOM order so MAIDR's index-based highlighting matches the visible chart.
