.. py:function:: create_graphical_operator(owner, name, path, visibility = VK.PUBLIC, symbol_file = None, state = False)

   
   Create an operator with a graphical diagram.

   The operator has a name.

   :Parameters:

       **owner** : :obj:`suite.Package`
           Owner of the operator, which is either the model itself or a package.

       **name** : :class:`python:str`
           Name of the operator.

       **path** : :obj:`Path`, default: :data:`python:None`
           Path of the file for storing the operator. This parameter is optional
           if the package's owner is a package. When the path is ``None`` and owner
           is the model, the operator is stored in the model's default file.

       **visibility** : :obj:`VK`, default: :obj:`PUBLIC`
           Accessibility of the operator.

       **symbol_file** : :obj:`Path`, default: :data:`python:None`
           Path of the file defining the symbol of the operator.

       **state** : :ref:`bool <python:bltin-boolean-values>`, default: :data:`python:False`
           Whether the operator is a node.

   :Returns:

       :obj:`suite.Operator`
