In the view dependencies tree you see views that depends on the selected view
but also views that depends on the dependent views.
The image above show you a good example.
Viewalyzer search the selected view recursivly for dependent views and show it here. That are the views that will be recompiled,
if you recompile the selected view, too.
Let me explain:
The view v_viewalyzer is the master view.
The view v_depend_on_v_viewalyzer depends on the master view v_viewalyzer but we have another view v_depend2 that depends on
v_depend_on_v_viewalyzer.
