 """
 Basic example to show how to turn a set of points into a surface, assign values,
 and plot it using PyVista.

 Points are stored in "data.csv". Points are structured and it's possible, though
 slightly harder, to create a pyvista.StructuredGrid using them. Instead, its
 much easier to simply to use the delaunay_2d filter.
