Copernicus Global Ocean Model Example
=====================================

This example demonstrates how to:

- Build a request to the **Copernicus Marine Service (CMEMS)**,
- Download a subset of the **global ocean physics model**,
- Visualise physical fields (salinity, temperature, SSH, currents),
- Plot surface currents with and without vectors,
- Save diagnostic plots automatically.

The example uses the :class:`visusat.copernicus.CopernicusRequest` class and high-level plotting utilities.
