LFRic Mesh (Projected)
----------------------

This example demonstrates how to render a projected unstructured quadrilateral mesh.

📋 Summary
^^^^^^^^^^

Creates a mesh from 1-D latitude and longitude unstructured points and connectivity.

The resulting mesh contains quad cells. The connectivity is required to construct
the cells by indexing into the CF UGRID unstructured points.

It uses an unstructured Met Office LFRic C48 cubed-sphere of surface temperature
data located on the mesh faces/cells.

Note that, a threshold is also applied to remove land ``NaN`` cells. A Natural Earth
base layer is also rendered along with Natural Earth coastlines and a graticule.
The mesh is also transformed to the Bonne projection.
