Doughnut
The [ObservableObject], [ObservableProperty] and [RelayCommand] attributes come from the
CommunityToolkit.Mvvm package, you can read more about it
here.
This web site wraps every sample using a UserControl instance, but LiveCharts controls can be used inside any container.
View model
using LiveChartsCore;
using CommunityToolkit.Mvvm.ComponentModel;
using System.Collections.Generic;

namespace ViewModelsSamples.Pies.Doughnut;
public partial class ViewModel : ObservableObject
{
// you can convert any array, list or IEnumerable<T> to a pie series collection:
public IEnumerable<ISeries> Series { get; set; } =
new[] { 2, 4, 1, 4, 3 }.AsPieSeries((value, series) =>
{
series.MaxRadialColumnWidth = 60;
});
