class_docstr: The citation graph dataset, including cora, citeseer and pubmeb.
  Nodes mean authors and edges mean citation relationships.
  
  Parameters
  -----------
  name: str
    name can be 'cora', 'citeseer' or 'pubmed'.
  raw_dir : str
      Raw file directory to download/contains the input data directory.
      Default: ~/.dgl/
  force_reload : bool
      Whether to reload the dataset. Default: False
  verbose : bool
      Whether to print out progress information. Default: True.
  reverse_edge : bool
      Whether to add reverse edges in graph. Default: True.
  transform : callable, optional
      A transform that takes in a :class:`~dgl.DGLGraph` object and returns
      a transformed version. The :class:`~dgl.DGLGraph` object will be
      transformed before every access.
  reorder : bool
      Whether to reorder the graph using :func:`~dgl.reorder_graph`. Default: False.
