"""Create a polygonal disk with a hole in the center.
The disk has zero height. The user can specify the inner and outer
radius of the disk, and the radial and circumferential resolution
of the polygonal representation.
Parameters
----------
center : iterable
Center in ``[x, y, z]``. Middle of the axis of the disc.
inner : float, optional
The inner radius.
outer : float, optional
The outer radius.
normal : iterable
Direction vector in ``[x, y, z]``. Orientation vector of the disc.
r_res : int, optional
Number of points in radial direction.
c_res : int, optional
Number of points in circumferential direction.
Returns
-------
pyvista.PolyData
Disk mesh.
Examples
--------
Create a disc with 50 points in the circumferential direction.
>>> import pyvista
>>> mesh = pyvista.Disc(c_res=50)
>>> mesh.plot(show_edges=True, line_width=5)
