Nodal graphs are commonly used in rigging, the process, or rather the art of making simple controls for complex actions. The combinations of these nodes and their symbolic links create networks known as 'graphs. Each node signifies an item, an operation or a function and its associated channels. In the Schematic viewport, users work with nodes, simple 2D representations of items that exist only within the Schematic. This is, in a way, like a graphic programming paradigm, where users define a flow of information through the network of elements visually. This particular activity is better suited to the 'Schematic Editor', where elements are visually linked, providing a more intuitive and powerful way to define relationships between elements building networks of operations that combine to produce a specific result. This is great for laying out models and scenes, but not so useful for setting up relationships between Items and their Channels. The 3D viewports give users a means to visually manipulate items and their geometric components relative to their 3D environment.
