class_docstr: A variety of attributed graph datasets from the
  `"Scaling Attributed Network Embedding to Massive Graphs"
  <https://arxiv.org/abs/2009.00826>`_ paper.
  
  Args:
      root (str): Root directory where the dataset should be saved.
      name (str): The name of the dataset (:obj:`"Wiki"`, :obj:`"Cora"`
          :obj:`"CiteSeer"`, :obj:`"PubMed"`, :obj:`"BlogCatalog"`,
          :obj:`"PPI"`, :obj:`"Flickr"`, :obj:`"Facebook"`, :obj:`"Twitter"`,
          :obj:`"TWeibo"`, :obj:`"MAG"`).
      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`)
