However, traditional visualization techniques often fall short of expectations or are altogether inadequate for new programming paradigms, such as Constraint Logic Programming (CLP), whose declarative and operational semantics differ in some crucial ways from those of other paradigms. In particular, traditional ideas regarding flow control and the behavior of data often cannot be lifted in a straightforward way to (C)LP from other families of programming languages. In this paper we discuss techniques for visualizing program execution and data evolution in CLP. We briefly review some previously proposed visualization paradigms, and also propose a number of (to our knowledge) novel ones. The graphical representations have been chosen based on the perceived needs of a programmer trying to analyze the behavior and characteristics of an execution. In particular, we concéntrate on the representation of the program execution behavior (control), the runtime valúes of the variables, and the runtime constraints. Given our interest in visualizing large executions, we also pay attention to abstraction techniques, Le., techniques which are intended to help in reducing the complexity of the visual information. date_type: published date: 1998 pages: 469 event_title: Joint Conference on Declarative Programming, APPIA-GULP-PRODE'98 event_location: A Coruña, Spain event_dates: July 20-23, 1998 event_type: conference institution: Informatica department: Inteligencia_Artificial refereed: TRUE book_title: APPIA-GULP-PRODE citation: Carro Liñares, Manuel and Hermenegildo, Manuel V.
