@yvonnefroehlich Could you please also include the image in the notebooks, which can make review easier.

I have included the output images within the notebooks for all PRs.

During preparing the AGU24 preworkshop we faced an issue with the review of JNs using gitnotebooks, please see GenericMappingTools/agu24workshop#9 (comment). It looks like that images lead to large diffs and for some JNs these diffs become too large and reviewing the JNs failed, but it worked when not showing the output images (less usage of fig.show or apply “clear all cells” before committing).
