  \addindex DOT_GRAPH_MAX_NODES
  The \c MAX_DOT_GRAPH_MAX_NODES tag can be used to set the maximum number of 
- nodes that will be shown in the graph. If the number of nodes in a graph 
- becomes larger than this value, doxygen will truncate the graph, which is
- visualized by representing a node as a red box. Note that doxygen will always 
- show the root nodes and its direct children regardless of this setting. 
+ nodes that will be shown in the graph. If the number of nodes in a graph
+ becomes larger than this value, doxygen will truncate the graph, which is 
+ visualized by representing a node as a red box. Note that doxygen if the number
+ of direct children of the root node in a graph is already larger than
+ \c MAX_DOT_GRAPH_NOTES then the graph will not be shown at all. Also note
+ that the size of a graph can be further restricted by \c MAX_DOT_GRAPH_DEPTH.

+ \addindex MAX_DOT_GRAPH_DEPTH
+ The \c MAX_DOT_GRAPH_DEPTH tag can be used to set the maximum depth of the 
+ graphs generated by dot. A depth value of 3 means that only nodes reachable
+ from the root by following a path via at most 3 edges will be shown. Nodes
+ that lay further from the root node will be omitted. Note that setting this
+ option to 1 or 2 may greatly reduce the computation time needed for large
+ code bases. Also note that the size of a graph can be further restricted by
+ \c DOT_GRAPH_MAX_NODES. Using a depth of 0 means no depth restriction (the default).
