An object diagram is a graph of instances, including objects and data values. A static object diagram
is an instance of a class diagram; it shows a snapshot of the detailed state of a system at a point in
time. The use of object diagrams is fairly limited, mainly to show examples of data structures.
Tools need not support a separate format for object diagrams. Class diagrams can contain objects,
so a class diagram with objects and no classes is an "object diagram." The phrase is useful, however,
to characterize a particular usage achievable in various ways.
