        Add a :class:`Node` to the model.

        :param node:
            The plain-text identifier for the nodeself.
            Can also be the :class:`Node` to retain backward compatibility.

        :param content:
            The display form of the variable.

        :param x:
            The x-coordinate of the node in *model units*.

        :param y:
            The y-coordinate of the node.

        :param scale: (optional)
            The diameter (or height) of the node measured in multiples of
            ``node_unit`` as defined by the :class:`PGM` object.

        :param aspect: (optional)
            The aspect ratio width/height for elliptical nodes; default 1.

        :param observed: (optional)
            Should this be a conditioned variable?

        :param fixed: (optional)
            Should this be a fixed (not permitted to vary) variable?
            If `True`, modifies or over-rides ``diameter``, ``offset``,
            ``facecolor``, and a few other ``plot_params`` settings.
            This setting conflicts with ``observed``.

        :param alternate: (optional)
            Should this use the alternate style?

        :param offset: (optional)
            The ``(dx, dy)`` offset of the label (in points) from the default
            centered position.

        :param fontsize: (optional)
            The fontsize to use.
