+the @uref{http://graphviz.org/, Graphviz} suite of programs for
+visualising graphs, as well as functions to call those programs.
+Main features of the graphviz library include:
+
+@enumerate
+@item Almost complete coverage of all Graphviz attributes and syntax
+@item Support for specifying clusters
+@item The ability to use a custom node type
+@item Functions for running a Graphviz layout tool with all specified output types
+@item Generate and parse Dot code with two options: strict and liberal
+@item Functions to convert FGL graphs and other graph-like data structures
+@item Round-trip support for passing an FGL graph through Graphviz to augment node
+and edge labels with positional information, etc.
+@end enumerate\n")
