A synergistic approach to specifying simple number independent layouts by example

ABSTRACT

A grid-based technique to specify simple number independent layouts by example is described. This technique was originally developed to support layout specification for a parallel program visualization system but can be applied to aid other simple graphical layout tasks as well. The technique works by allowing the user to construct an example layout using a grid-based interaction technique. This example can then be generalized into a layout algorithm which can be applied to create layouts of any size. However, rather than simply choosing the “best” generalization, the system described here takes a synergistic approach. New examples from a set of alternative generalizations are presented to the user so that they can guide and control the generalization process. This provides more understanding and control of the generalization to be constructed from only one small example.
