=======================
Simple Anchored Artists
=======================

This example illustrates the use of the anchored helper classes found in
:mod:`matplotlib.offsetbox` and in :mod:`mpl_toolkits.axes_grid1`.
An implementation of a similar figure, but without use of the toolkit,
can be found in :doc:`/gallery/misc/anchored_artists`.
