JHAVE: supporting algorithm visualization

JHAVE fosters the use of algorithm visualization as an effective pedagogical tool for computer science educators, helping students to better understand algorithms. The Java-hosted algorithm visualization environment (JHAVE) is not an AV system itself but rather a support environment for a variety of AV systems (called AV engines by JHAVE). In broad terms, JHAVE gives such an engine a drawing context on which it can render its pictures in any way. In return, JHAVE provides the engine with effortless ways to synchronize its graphical displays with i) a standard set of VCR-like controls, ii) information and pseudocode windows, iii) input generators, iv) stop-and-think questions, and v) meaningful content generation tools.
