Realizing XML Driven Algorithm Visualization

AbstractIn this paper we describe work in progress on JHAVÉ-II, a new generation of the client-server based algorithm visualization system JHAVÉ. We believe this to be the first algorithm visualization system to be totally XML driven. We describe the XML scripting language visualization authors can use with JHAVÉ-II to define the sequence of graphical snapshots, integrated pop-up questions, synchronized pseudocode, and supplemental information that comprise a particular algorithm visualization. JHAVÉ-II then uses these scripts to render visualizations and support student exploration of algorithms

Distributed Framework for Adaptive Explanatory Visualization

AbstractEducational tools designed to help students understand programming paradigms and learn programming languages are an important component of many academic curricula. This paper presents the architecture of a distributed event-based visualization system. We describe specialized content provision and visualization services and present two communication protocols in an attempt to explore the possibility of a standardized language
