Plot and save a 2D DataArray over longitude and latitude using Cartopy.

This function creates a geographically-aware color plot using a discrete colormap, with automatic colorbar extensions when values fall outside the given [vmin, vmax].

Parameters:

data (xr.DataArray) – 2D input data with ‘lon’ and ‘lat’ coordinates.
cb_label (str) – Label for the colorbar.
title (str) – Title of the plot.
out_path (Path) – Path where the figure will be saved.
cmap (str, optional) – Name of the Matplotlib colormap to use.
x_min, x_max, y_min, y_max (float, optional) – Manual spatial limits for zooming.
vmin, vmax (float, optional) – Color scale limits. If not provided, data min/max are used.
