    Algorithm animation is a form of program visualization that is concerned with dynamic and interactive graphical displays of a program's fundamental operations. The paper describes the Zeus algorithm animation system. Zeus is noteworthy for its use of objects, strong-typing, parallelism, and graphical development of views. Also of interest is how the system can be used for building multi-view edito... View full abstract»

    Visual languages have motivated growing interests in the investigation of grammatical formalisms and parsing algorithms for modelling and recognizing multidimensional structures. The effectiveness of visual languages require that some efforts must be accomplished to obtain efficient parsing techniques. A general parsing scheme for relation grammars is presented. The class RG/1 of grammars is chara... View full abstract»

    Visual languages provide syntactic features to depict graphs explicitly: they offer an alternative to text for the denotation of structures of relations. The language viz was therefore devised to provide a means for visualizing relational specifications and programs. The increased understanding of object-oriented program design makes it sensible to enhance viz to cope with this style, and so provi... View full abstract»

    The paper describes the conceptual model and specification method for a visualization environment concerned with exploring, monitoring, and presenting concurrent computations. The model is declarative in that visualization is treated as a mapping from program states to a three-dimensional geometric world. The state-to-geometry mapping is defined as a composition of several simpler mappings. This p... View full abstract»
