Visualization Techniques for Various Programming Paradigms

This paper illustrates the variety of visualization techniques that are employed for various programming paradigms, examining the type of information required and the advantages that the information provides the programmer. We examine the specific visualization requirements for each paradigm and the general requirements of visualization systems which depict the flow of control for both sequential and parallel program execution. We find that many of the visualization systems currently available tend to focus on only one aspect of the visualization requirements rather than the broad base of needs of the programmer. The need to integrate these visualization systems in the future is highlighted. 1. INTRODUCTION Program visualization focuses on the graphical representation of an executing program and its data. This information is presented in a form designed to enhance both the understanding and productivity of the programmer through the efficient use of the human visual system. The progra..
