+
+PyVista is a helper module for the Visualization Toolkit (VTK) that wraps the
+VTK library through NumPy and direct array access through a variety of methods
+and classes.  This package provides a Pythonic, well-documented interface
+exposing VTK's powerful visualization backend to facilitate rapid prototyping,
+analysis, and visual integration of spatially referenced datasets.")
