Moreno, C. A., Bischof, W. F., and Hoover, H. J. (2012). Interactive visualization of dependencies. Computers & Education, 58, 1296-1307.
We present an interactive tool for browsing course requisites as a case study of dependency visualization. This tool uses multiple interactive visualizations to allow the user to explore the dependencies between courses. A usability study revealed that the proposed browser provides significant advantages over traditional methods, in terms of learnability, efficiency and user confidence. The results are discussed within a general framework for interactive visualization of dependencies.
