Initially display no chart data for real time updates

Question

Apologies if this has been already asked elsewhere, I couldn't find any reference.

I'd like to use Vico for displaying some real time data, which means that the initial graph state would have no data.
I'd need it to just show the cartesian chart grid, set to a certain span of values as provided by CartesianLayerRangeProvider.fixed (providing all four values minY, maxY, minX, maxX to be non-null).
It would then be updated upon running a new transaction with the chart model producer when the data is created.

However, I haven't been able to get that working, as if I pass no data, the chart completely disappears, leaving no grid either.

Here's what I'm using at the moment:

    val modelProducer = remember { CartesianChartModelProducer() }

    val dataTransaction: CartesianChartModelProducer.Transaction.() -> Unit = {
        columnSeries { series(emptyList()) } // this completely hides the chart
    }

        runBlocking {
            modelProducer.runTransaction(dataTransaction)
        }

CartesianChartHost(
        chart = rememberCartesianChart(
            rememberColumnCartesianLayer(
                ... // other styling omitted
                rangeProvider = CartesianLayerRangeProvider.fixed(minY = -10, maxY = 10, minX = -10.0, maxX = 10.0),
                startAxis = VerticalAxis.rememberStart(...),
                bottomAxis = HorizontalAxis.rememberBottom(...),
                modelProducer = modelProducer
            )
        )
)

But I see there are empty state checks in ColumnCartesianLayerModel that cause an exception to be thrown.

What am I doing wrong?
Couldn't find anything about this scenario in the docs or tutorials either.

Thanks in advance for your help.
