+The mplot3d toolkit adds simple 3D plotting capabilities (scatter, surface,
+line, mesh, etc.) to Matplotlib by supplying an Axes object that can create
+a 2D projection of a 3D scene.  The resulting graph will have the same look
+and feel as regular 2D plots.  Not the fastest or most feature complete 3D
+library out there, but it ships with Matplotlib and thus may be a lighter
+weight solution for some use cases.
+
+See the :doc:`mplot3d tutorial </tutorials/toolkits/mplot3d>` for
+more information.

+
+The interactive backends also provide the ability to rotate and zoom the 3D
+scene.  One can rotate the 3D scene by simply clicking-and-dragging the scene.
+Zooming is done by right-clicking the scene and dragging the mouse up and down
+(unlike 2D plots, the toolbar zoom button is not used).
