Description of proposed changes

Fixes #3320

Preview: https://pygmt-dev--3711.org.readthedocs.build/en/3711/gallery/lines/linestrings.html#

Reminders

• Run make format and make check to make sure the code follows the style guide.
• Add tests for new features or tests that would have caught the bug that you're fixing.
• Add new public functions/methods/classes to doc/api/index.rst.
• Write detailed docstrings for all functions/methods.
• If wrapping a new module, open a 'Wrap new GMT module' issue and submit reasonably-sized PRs.
• If adding new functionality, add an example to docstrings or tutorials.
• Use underscores (not hyphens) in names of Python files and directories.

Slash Commands

You can write slash commands (/command) in the first line of a comment to perform
specific operations. Supported slash command is:

• /format: automatically format and lint the code

Two thoughts:

1. Perhaps we should have geodatasets installed in our CI, so that we don't have to have the long URL hardcoded.
2. The title "Rivers" gives me the expression that this is about a river dataset, but actually it's all about plotting LineString/MultiLineString geometries in GeoPandas objects (or geojson format). Maybe rename the title to something like "Plotting lines with LineString/MultiLineString geometry", "GeoPandas: Lines with LineString/MultiLineString geometry"

Agree with both points. Regarding point 1 we just want to add it for the docs/gallery example and not as an general dependency, right?

Yes.

Regarding point 1, this would be also relevant / helpful for the Gallery example Choropleth map.

Maybe we should add geodatasets and update the Choropleth example in a separate PR first.

I'll open a PR in minites.

[seisman]

I'm wondering if it makes more sense to change the title to:

GeoPandas: Plotting lines with LineString/MultiLineString geometry

Suggested change

	:func:`geopandas.read_file` to load data from any supported OGR format such as

Please wrap these lines to 88 characters.

Check the content of the data before plotting.

Suggested change

	gdf = gdf.to_crs("EPSG:4326")
	gdf = gdf.to_crs("EPSG:4326")
	print(gdf)
