19/// \brief Demo of the graph grawing function \ref graphToEps()
20///
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 "graphmapfactory".
