Tutorial 2 - scientific Python ecosystem: pandas and GeoPandas: Add JN

[yvonnefroehlich]

This PR adds the Jupyter notebook for Tutorial 2 - scientific Python ecosystem: pandas and GeoPandas:

• Data stored as pandas DataFrame and GeoPandas GeoDataFrame
• Different geometries (point, lines, polygons)
• Choropleth map
• Handling aspatial data
• Filtering and using different styles / files for plotting
• Conversion of objects from other python packages to geopandas related objects

Notebook looks very clean and easy to follow so far! Just some minor suggestions for now, not sure if you're planning to add more materials to this notebook?

Thanks @weiji14 for already looking at this JN and the positive feedback! I feel the general structure should be finished. What is missing is some documentation and improvements of the formulations, as you already suggested.

Just a simple suggestion, using individual cells can help beginners understand how to set a region.
For example, they can observe the data range beforehand through print(df_jp_eqs["magnitude"].min(), df_jp_eqs["magnitude"].max()) to demonstrates how to visualize data limits.

This is a good suggestions! Moved these lines to a separate cell.

I think is ready to merge. My only minor suggestion would be to add a frame to the choropleth map.

Maybe it's better to add the file names of the JNs or files together within one PR to avoid merge conflicts.

[weiji14]

Let's just leave it as is, it'll be a good example to learn how to handle merge conflicts 🙂

[yvonnefroehlich]

Same as above, maybe better to update the environment.yml within one PR for all tutorials to avoid merge conflicts.

Since pandas is a required dependency of pygmt, this won't need to be added here, unless you specifically require pandas=2.2.2?

Note that I'll be updating the conda-lock.yml file to pin all dependencies once all the tutorial notebooks are merged, so that people can reproduce the exact dependency versions in the future (including pandas).

I don't think I specifically need this pandas version. Just added the version I am currently having installed in the virtual environment I am using for this pre-workshop.
