+A filled gray box represents the struct or class for which the graph is generated. </li>

+A box with a black border denotes a documented struct or class. </li>

+A box with a gray border denotes an undocumented struct or class. </li>

+A dark green arrow is used for protected inheritance. </li>
+<li>
+A dark red arrow is used for private inheritance. </li>
