class_docstr: The condensed tree structure, which provides a simplified or smoothed version
  of the :class:`~hdbscan.plots.SingleLinkageTree`.
  
  Parameters
  ----------
  condensed_tree_array : numpy recarray from :class:`~hdbscan.HDBSCAN`
      The raw numpy rec array version of the condensed tree as produced
      internally by hdbscan.
  
  cluster_selection_method : string, optional (default 'eom')
      The method of selecting clusters. One of 'eom' or 'leaf'
  
  allow_single_cluster : Boolean, optional (default False)
      Whether to allow the root cluster as the only selected cluster
