To begin the interactive data structure visualizations, select one of the visualizations from the menu at the left of the screen. There are several groups of visualizations including binary trees, directed graphs, and sorting. Each contains a variety of data structure topics.
Once you have selected a topic explanatory text related to that topic will appear in this window. If you wish to view the visualization, click the appropriate button at the bottom of the screen. A new window will be displayed containing the visualization. Clicking the button labeled Ada Code will cause the Ada code for that topic to be displayed in this window.
