Thanks for opening this issue. I agree that this would be a helpful example. Do you have a dataset in mind for the example that you would like added to...

Regarding the CI issue raised in https://github.com/GenericMappingTools/pygmt/issues/1666#issuecomment-993962742, here are two options: 1. Use the [doctest skip directive](https://docs.pytest.org/en/latest/how-to/doctest.html#skipping-tests) to skip particular examples all the time. 2. Add a new target to...

> Should this only be for data processing modules that can't be as easily demonstrated as a plotting function, or should there be in-line examples for all of our modules?...

> > Just on this, do we want to run `make fulltest` (that includes all of these inline example doctests) on a semi-regular basis? E.g. every week or every month?...

> Looking through the examples in the GMT documentation and PyGMT tests, a few of them call remote datasets without using a PyGMT function (e.g. @Table_5_11_mean.xyz for surface). Should the...

``flake8`` would check for whitespace and lines >80 (both not caught by ``black`` in examples); currently ``flake8`` is only used for pygmt, setup.py, and doc/conf.py.

GMT does not yet support auto-generated legend items for custom symbols. This issue is being tracked upstream by https://github.com/GenericMappingTools/gmt/issues/1973.

@joa-quim how do you link the data to the `GMT_IS_IMAGE` family in GMT.jl? Is this done via `GMT_Put_Matrix` in the same way as for `GMT_IS_GRID`?
