The concept of a graphical type enables the specification of an external graphical presentation for ConceptBase objects. The graphical type is declared using a special pre-defined attribute category. An application program then uses this information to determine the graphical presentation of an object.
The next subsection introduces the basic concepts behind graphical types, while section B.2 presents the standard graphical type definitions for the ConceptBase Graph Browser. Section B.3 describes the definition of application-specific types.
