The visualizer is a utility that allows its user to graphically visualize many of the data structures used in jdsl. It can visualize the interactions of multiple structures at one time and keeps a history of the operations the user has performed on the data structures. It also has the capability to allow the outside user to add snapshots to the history in order to visualize algorithms.

It can be used as an educational tool allowing students to graphically see whether their implementation of a data structure or algorithm functions as they expect it to. It can also be used during the process of development of algorithm implementations.

The visualizer is a tool for use with the Library of Data Structures for Java (jdsl) which is produced by the Center for Geometric Computing (geomlib) at Brown University. It is recommended for use as an application with java 1.3.x Virtual Machines (it runs as an applet in AppletViewer, but not in most browsers), and utilizes the AWT and Networking packages.
