using Syncfusion.Maui.Core.Hosting;

public static class MauiProgram
{
    public static MauiApp CreateMauiApp()
    {
        var builder = MauiApp.CreateBuilder();
        builder
            .UseMauiApp<App>()
            .ConfigureSyncfusionCore();

        return builder.Build();
    }
}

2. Create a model and a ViewModel

using System.Collections.ObjectModel;

public class HierarchyData
{
    public string Name { get; set; }
    public double Value { get; set; }
    public ObservableCollection<HierarchyData> Children { get; set; }
}

public class SunburstViewModel
{
    public ObservableCollection<HierarchyData> HierarchyCollection { get; set; }

    public SunburstViewModel()
    {
        HierarchyCollection = new ObservableCollection<HierarchyData>
        {
            new HierarchyData 
            { 
                Name = "United States", 
                Value = 100,
                Children = new ObservableCollection<HierarchyData>
                {
                    new HierarchyData { Name = "California", Value = 60 },
                    new HierarchyData { Name = "New York", Value = 40 }
                }
            }

    </ContentPage.BindingContext>

    <syncfusion:SfSunburstChart ItemsSource="{Binding HierarchyCollection}"
                                ValueMemberPath="Value"
