hull defined by input data (no extrapolation is done).
Uses natural neighbor interpolation based on Delaunay triangulation.
+ By default, this algorithm is provided by the matplotlib.delaunay
+ package, written by Robert Kern. The triangulation algorithm in this
+ package is known to fail on some nearly pathological cases. For
+ this reason, a separate toolkit (mpl_tookits.natgrid) has been created
+ that provides a more robust algorithm fof triangulation and interpolation.
+ This toolkit is based on the NCAR natgrid library, which contains code
+ that is not redistributable under a BSD-compatible license. When
installed,
+ this function will use the mpl_toolkits.natgrid algorithm, otherwise it
+ will use the built-in matplotlib.delaunay package.
