Based on the manager, the grapher is a
natural extension of the manager concepts. A grapher is composed
of nodes and links.
A grapher is an instance of the IlvGrapher class, a subclass of the
IlvManager
class. The grapher library offers enhanced performance to create
programs, including a large quantity of dynamic interconnected
information, such as network management and file management
programs.
You have an extensive set of objects in the
grapher library for creating:
- Nodes: The visual reference points in a hierarchy of information. A node is a graphic object, an instance of a subclass of the IlvGraphic class.
- Links: The visual representation of connections between nodes. Links are also graphic objects, instances of the
IlvLinkImageclass or its subclasses.
Graphic objects in a manager can be visible or invisible. For
details, see Visibility.
The following example shows a grapher that connects

graphic objects (nodes). The lines in blue are node connections
(links).
