How to Change Data Label Connector Type in MAUI CircularChart?

The .NET MAUI Circular Chart allows you to modify the connector type of data labels for Pie and Doughnut series.
To change the connector type, use the ConnectorType property within ConnectorLineStyle. Specify the connector type, either Line or Curve. Setting it to Line connects data labels with straight lines, while setting it to Curve connects data labels with curved lines. By default, the data labels connect with straight lines.
The following code sample illustrates how to connect data labels with curved lines.

[XAML]

 <chart:SfCircularChart>
  . . .
     <chart:DoughnutSeries ItemsSource="{Binding Data}" 
                           ShowDataLabels="True"
                           XBindingPath="Product"
                           YBindingPath="SalesRate">
        <chart:DoughnutSeries.DataLabelSettings>
            <chart:CircularDataLabelSettings LabelPosition="Outside">
                <chart:CircularDataLabelSettings.ConnectorLineSettings>
                    <chart:ConnectorLineStyle ConnectorType="Curve"/>
                </chart:CircularDataLabelSettings.ConnectorLineSettings>
            </chart:CircularDataLabelSettings>
        </chart:DoughnutSeries.DataLabelSettings>
     </chart:DoughnutSeries>
 </chart:SfCircularChart>

[C#]

SfCircularChart chart = new SfCircularChart();
. . .
DoughnutSeries series = new DoughnutSeries()
{
    ItemsSource = viewModel.Data,
    XBindingPath = "Product",
    YBindingPath = "SalesRate",
    ShowDataLabels = true,
};

ConnectorLineStyle connectorLineStyle = new ConnectorLineStyle
{
    ConnectorType = ConnectorType.Curve
};

series.DataLabelSettings = new CircularDataLabelSettings()
{
    LabelPosition = ChartDataLabelPosition.Outside,
    ConnectorLineSettings = connectorLineStyle
};

chart.Series.Add(series);
