Unable to instantiate SKGeoMap

[mjanulaitis]

The bug I have a background WPF process that generates images for email notifications and scheduled reports. Currently I am able to generate line, bar, pie and stacked charts however when I try to create an SKGeoMap to create the chart so I can then call the SaveImage method and error is thrown.

To Reproduce Steps to reproduce the behavior:

1. Instantiate the following class:

   public class GeoMapChartControlEx
   {
       private ObservableCollection<HeatLandSeries> SeriesCollection { get; set; } = new();
   
       private readonly SKGeoMap chartCtrl = new();
   
       public GeoMapChartControlEx()
       {
           chartCtrl.Series = SeriesCollection;
       }
   
       public void SaveImage(ChartModel m, string outputFileName)
       {
           try
           {
               chartCtrl.Width = m.ChartOptionsModel.Width;
               chartCtrl.Height = m.ChartOptionsModel.Height;
   
               chartCtrl.CreateChart(m, SeriesCollection);
               chartCtrl.SaveImage(outputFileName);
           }
           catch (Exception ex)
           {
               MainViewModel.Instance.Log(ex);
           }
       }
   }

2. The following error is thrown: There is no a ChartEngine registered.

Expected behavior The ChartEngine should registered and the class successfully instantiated.

@beto-rodriguez Thanks for all your work on this project. The graphing is great. I used to write my own real-time graphing solutions using C++, Java then later C# but didn't have the time to mess with a solution for the projects I have been working on the last 6 years. I am in the process of porting my WPF app to Avalonia for use on RHEL, Ubuntu and CentOS and your live charts code integrated flawlessly. I will get this added to my project in the coming weeks.
