WPF Diagram (SfDiagram) support to customize the Visibility of Annotation. This can be achieved by using custom class from AnnotationEditorViewModel and ViewTemplate property of Annotation. We have provided code example, sample and screenshots to represent this.

//Annotation collection
node.Annotations = new ObservableCollection<AnnotationEditorViewModel>
{
  new Annotation()
  {
    Content="node",
    //set visibility as Hidden|Visible|Collapsed to Annotation content
    Visibility=Visibility.Collapsed,
    ViewTemplate=this.Resources["viewtemplate"] as DataTemplate
  }
};
