class LandAreaListDataAdapter : DXPieSeriesData {
    IReadOnlyList<LandAreaItem> landAreas;

    public CountryAreaData(IReadOnlyList<LandAreaItem> landAreas) {
        this.landAreas = landAreas;
    }

    public override int DataCount { get => landAreas.Count; }    
    public override getLabelByIndex(int index) => landAreas[index].CountryName;
    public func getValueByIndex(int index) => landAreas[index].LandArea;
}
class LandAreaItem {
    public string CountryName { get; }
    public double LandArea { get; }
