19 /// \brief Demo of the graph grawing function \ref graphToEps()
21 /// This demo program shows examples how to use the function \ref
22 /// graphToEps(). It takes no input but simply creates six
23 /// <tt>.eps</tt> files demonstrating the capability of \ref
24 /// graphToEps(), and showing how to draw directed/undirected graphs,
25 /// how to handle parallel egdes, how to change the properties (like
26 /// color, shape, size, title etc.) of nodes and edges individually
27 /// using appropriate \ref maps-page "graph maps".
