Title:
Real Clock Time Animation Support for Developing Software Visualizations
Authors:
John T. Stasko

Abstract:
Developers building software visualizations must use a graphics library
and user interface toolkit as an underlying support platform. Often,
these support environments are large, difficult to learn, low-level, and
lacking primitives for capabilities such as animation. We have developed
a graphics support environment called Polka-RC for building software
visualizations. Polka-RC is a second generation system that leverages
the continuous animation primitives of the mature system Polka, and adds
the capability of specifying real clock time-based animation activations
and durations. The new Polka-RC animation model also provides a flexible
multiprocess program-to-visualization mapping. In this article we
describe the Polka-RC methodology, list advantages of the approach, and
describe how the methodology influences the design of software visualizations
and algorithm animations.
