Akrti: a system for drawing data structure

A system for graphically displaying data structures created by programs during execution is described. Each built-in data type is displayed in a standard way. No additional programming on the part of the user is required to use the system. Special hints may be used, at run time, to declare record/point data structures as abstract data types (e.g. binary tree, linked list, stack, etc.). The drawing system uses these hints to invoke built-in algorithms to draw each abstract data type. If a record/point data structure does not fit into one of the special types, then it will be drawn as a graph. Picture attributes such as colors, orientation, and spacing can be changed by the user. Output can be displayed on either traditional terminals or through a window system
