BaseView
BaseView
The impl.View class is an optional base class for visualization views which implements the IView interface.
An application instantiates a view given a specification with the visualization model and the container HTML element.
The first update of the view must be explicitly triggered by a call to model.update.
Over time, the model may be mutated and, whenever its Update:{do} event is emitted, the view automatically updates itself.
The view translates user interaction by perform actions on the model. The standard actions are Select and Execute. There are sugar methods on the model to perform these, select and execute.
When a view is no longer needed, the application must call its dispose method, so that the view can free held resources and not cause memory-leaks.
