Transport of semantic information within programm visualization

Aim of the project is the development of a system which generates a visualization of programs at runtime without adding additional code to these programs. Furthermore, the user should be able to influence the visualization and to change the presentation of the data, not only with respect to their position, but especially with respect to the degree of aggregation. In contrast to existing systems, the data are not presented as a sequence of numbers (the style usually adopted by debuggers), but based on semantic information extracted from the data.
