This sample uses C# 12 features, it also uses features from the CommunityToolkit.Mvvm package, you can learn more about it here.

This web site wraps every sample using a ContentPage instance, but LiveCharts controls can be used inside any container.

    // 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) =>
        {
