The result is animated when changes occur, as when a node is added to a linked list. Common data structures are automatically identified and displayed structurally. Other viewers show, for example, a

Complexity Profile Graph (CPG) is a statement-level complexity diagram. Its purpose is to aid in identifying overly complex areas of source code. jGRASP generates CPGs for both Java and Ada. The metric includes common measures, such as

and other objects and primitives during debugging and workbench operations. For example, a content-based view shows ArrayList and LinkedList in an identical way, as a list of elements. Structural views show the internal structure of
