The Microsoft DirectX SDK provides a very useful debugging utility
called GraphEdit, which can be used to simulate graph building.
From the Graph menu of the GraphEdit application, click Insert
Filters... and choose the desired filters. Filters are organized by
categories. Click Insert Filter button to add the filters to a graph.
Then connect two filters' pins by dragging mouse from one filter's
output pin to another filter's input pin. An arrow will be drawn if
these two pins agree on the connection.
