Nodes

The scenegraph is a directional acyclic graph. It contains many nodes. Each node has a right-click menu, whose entries depend on the type of the node. Figure 5-1 is a scenegraph snapshot.

Nodes in Figure 5-1 can be divided into 2 categories with the deciding factor if there is a triangle to their left:

Alternatively, nodes in the scenegraph can be divided into 3 main categories according to what type of objects they represent: collections (data sets), viewports (plots), and dialogs.

Left clicking a non-hidden, non-collection node in the scenegraph will make the corresponding window rise to the top. Making the window of a plot, a list view, or a non-modal dialog the focused window (for example, clicking its title bar) will highlight the corresponding node in the scenegraph.
