class_docstr: The WebKB datasets used in the
  `"Geom-GCN: Geometric Graph Convolutional Networks"
  <https://openreview.net/forum?id=S1e2agrFvS>`_ paper.
  Nodes represent web pages and edges represent hyperlinks between them.
  Node features are the bag-of-words representation of web pages.
  The task is to classify the nodes into one of the five categories, student,
  project, course, staff, and faculty.
  
  Args:
      root (str): Root directory where the dataset should be saved.
      name (str): The name of the dataset (:obj:`"Cornell"`, :obj:`"Texas"`,
          :obj:`"Wisconsin"`).
      transform (callable, optional): A function/transform that takes in an
          :obj:`torch_geometric.data.Data` object and returns a transformed
          version. The data object will be transformed before every access.
          (default: :obj:`None`)
      pre_transform (callable, optional): A function/transform that takes in
          an :obj:`torch_geometric.data.Data` object and returns a
          transformed version. The data object will be transformed before
          being saved to disk. (default: :obj:`None`)
      force_reload (bool, optional): Whether to re-process the dataset.
          (default: :obj:`False`)
