    Example
    Create a Heatmap Renderer
    string colorBrewerSchemesName = "ArcGIS Colors";
    StyleProjectItem style = Project.Current.GetItems<StyleProjectItem>().First(s => s.Name == colorBrewerSchemesName);
    string colorRampName = "Heat Map 4 - Semitransparent";
    IList<ColorRampStyleItem> colorRampList = await QueuedTask.Run(() =>
    {
      return style.SearchColorRamps(colorRampName);
    });
    ColorRampStyleItem colorRamp = colorRampList[0];
    
    await QueuedTask.Run(() =>
    {
      //defining a heatmap renderer that uses values from Population field as the weights
      HeatMapRendererDefinition heatMapDef = new HeatMapRendererDefinition()
      {
        Radius = 20,
        WeightField = "Population",
        ColorRamp = colorRamp.ColorRamp,
        RendereringQuality = 8,
        UpperLabel = "High Density",
        LowerLabel = "Low Density"
      };
    
      FeatureLayer flyr = MapView.Active.Map.Layers[0] as FeatureLayer;
      CIMHeatMapRenderer heatMapRndr = flyr.CreateRenderer(heatMapDef) as CIMHeatMapRenderer;
      flyr.SetRenderer(heatMapRndr);
    });
