 Matplotlib has two interfaces. For an explanation of the trade-offs between the
-implicit and explicit interfaces see :ref:`api_interfaces`.
+explicit and implicit interfaces see :ref:`api_interfaces`.
 
-The first is an explicit object-oriented (OO) interface. In this case, we
-utilize an instance of :class:`axes.Axes` in order to render visualizations on
-an instance of :class:`figure.Figure`.  The second is based on MATLAB and uses
-an implicit global state-based interface.  This is encapsulated in the
-:mod:`.pyplot` module. See the :doc:`pyplot tutorials
