Components of the graph

The graph diagram provides a comprehensive visualization solution that enables the ability to easily visualize relationships between different components. An extensive library of graphics display the relationship in a variety of views. You can customize the views to fit your organization, including using your own graphics for display. You can view, add, or update relationships using the graphical interface. The main components of the graph diagram are:


A mathematical structure used to model relationships between objects from a certain collection.


Representation of an entity. Nodes are defined by an ID and at a minimum require that either a bounding shape or an icon be defined so they are visible in the graph. Nodes can be joined by an edge (which also has an ID) by specifying the IDs of the joined nodes as the "to" and "from" attribute values of the node edge. Line styles and colors are optional.


Represents a relationship between two nodes. An edge is usually depicted as a line connecting its end nodes. An arrowhead at the target end of the line indicates the destination of a directed edge.
