Toolkits are collections of application-specific functions that extend Matplotlib.
mpl_toolkits.mplot3d
provides some basic 3D
plotting (scatter, surf, line, mesh) tools. 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. Check out the
mplot3d tutorial for more
information.
The mpl_toolkits.axes_grid1
toolkit is a
collection of helper classes for displaying multiple axes in Matplotlib.
The mpl_toolkits.axisartist
toolkit contains
a custom Axes class that is meant to support curvilinear grids.
