A graph is a collection of DirectShow filters connected to each other. MediaPortal creates DirectShow graphs for viewing Movies, DVD's and TV, listening to radio and transcoding or compression of recorded TV shows.
GraphEdit is an advanced utility which allows you to create DirectShow grraphs, test installed DirectShow filters and connect to graphs rendered by other applications.
You can also use GraphEdit to inspect any type of DirectShow filter installed on your system.
Graphstudio is an open source alternative to GraphEdit
