            <!--Setting BindingContext-->

            <!--Initialize the horizontal axis for the .NET MAUI Cartesian Chart.-->

            <!--Initialize the vertical axis for the .NET MAUI Cartesian Chart.-->
            <!--Adding Spline Series to the .NET MAUI Cartesian Chart.-->
                        ItemsSource="{Binding Data}" 
public class Model
    public string Month { get; set; }

    public double Target { get; set; }
