class_docstr: Graph source code in the DOT language.
  
  Args:
      name: Graph name used in the source code.
      comment: Comment added to the first line of the source.
      filename: Filename for saving the source
          (defaults to ``name`` + ``'.gv'``).
      directory: (Sub)directory for source saving and rendering.
      format: Rendering output format (``'pdf'``, ``'png'``, ...).
      engine: Layout command used (``'dot'``, ``'neato'``, ...).
      renderer: Output renderer used (``'cairo'``, ``'gd'``, ...).
      formatter: Output formatter used (``'cairo'``, ``'gd'``, ...).
      encoding: Encoding for saving the source.
      graph_attr: Mapping of ``(attribute, value)`` pairs for the graph.
      node_attr: Mapping of ``(attribute, value)`` pairs set for all nodes.
      edge_attr: Mapping of ``(attribute, value)`` pairs set for all edges.
      body: Iterable of verbatim lines (including their final newline)
          to add to the graph ``body``.
      strict (bool): Rendering should merge multi-edges.
  
  Note:
      All parameters are `optional` and can be changed under their
      corresponding attribute name after instance creation.
