Function Signature

@Composable
fun CurveLineChart(
    dataCollection: ChartDataCollection,
    modifier: Modifier = Modifier,
    padding: Dp = 16.dp,
    axisConfig: AxisConfig = ChartDefaults.axisConfigDefaults(),
    radiusScale: Float = 0.02f,
    lineConfig: LineConfig = LineChartDefaults.defaultConfig(),
    chartColors: CurvedLineChartColors = CurvedLineChartDefaults.defaultColor(),
) {
    //Implementation
}

Parameters
