* @class vtkGraphReader
* @brief read vtkGraph data file
*
* vtkGraphReader is a source object that reads ASCII or binary
* vtkGraph data files in vtk format. (see text for format details).
* The output of this reader is a single vtkGraph data object.
* The superclass of this class, vtkDataReader, provides many methods for
* controlling the reading of the data file, see vtkDataReader for more
* information.
* @warning
* Binary files written on one system may not be readable on other systems.
