protected createKpiStack(transitMapView: TransitMapView): HtmlView {
    const kpiStack = HtmlView.fromTag("div")
        .key("kpiStack")
        .position("absolute")
        .right(0)
        .top(0)
        .bottom(0)
        .zIndex(9)
        .pointerEvents("none");

    const vehicleFlowKpi = kpiStack.append("div")
        .key("vehicleFlowKpi")
        .position("absolute")
        .borderRadius(8)
        .boxSizing("border-box")
        .backgroundColor(Color.parse("#070813").alpha(0.33))
        .backdropFilter("blur(2px)")
        .pointerEvents("auto");
