# ViewModel

### Purpose
This module provides `PropertyViewModel`, a view model for displaying and managing graph property views. It integrates with the Prism framework for event aggregation, region management, and interaction requests (notifications/confirmations). It acts as a bridge between property views and the broader application infrastructure.

### Public Interface

- **`PropertyViewModel`** (class)
  - Inherits from: `BaseViewModel<IGraphPropertyViewModel>`, implements `IPropertyViewModel`

  **Constructor:**
  - **`PropertyViewModel(IPropertyView view, IRegionManager regionManager, IEventAggregator eventAggregator, IUnityContainer unityContainer)`** - Initializes the view model, sets up the view's DataContext, creates interaction requests, and subscribes to `RaiseNotification` events.

  **Properties:**
  - **`IPropertyView View { get; }`** - Gets the associated view instance.
  - **`InteractionRequest<Notification> NotificationRequest { get; }`** - Interaction request for displaying notifications.
  - **`InteractionRequest<Confirmation> ConfirmationRequest { get; }`** - Interaction request for displaying confirmations.
  - **`object Properties { get; set; }`** - Gets or sets the properties object. Raises `PropertyChanged` event when set.
  - **`string HeaderInfo { get; }`** - Returns the constant string "Graph Property".
  - **`bool IsBusy { get; set; }`** - Throws `NotImplementedException`
