The Visual Navigator uses node depth levels from 0 to 5 to render the depth of the graphs. You can use these levels to control the scope of information that is displayed on a graph. At level 0, no relationships are displayed between a selected object and its references. Level 5 represents the most complex object relationships.

For example, if you have classes A, B, C, and D, with the following relationship: A > B > C > D, and you want to render graphs at different levels, the following table shows the classes that will be displayed at the different node depth levels you select.
