Describe the Bug

We don't create those pngs when running in the following block: else: print( "The following countries have no existing Natural Gas network between the chosen bus regions:\n"

• ", ".join(bus_regions_onshore.country.unique().tolist()) )

  # Create an empty DataFrame with the specified column names
  pipelines = {"bus0": [], "bus1": [], "capacity": [], "length": [], "GWKm": []}
  
  pipelines = pd.DataFrame(pipelines)
  pipelines.to_csv(snakemake.output.clustered_gas_network, index=False)

Error Message

Waiting at most 5 seconds for missing files.
MissingOutputException in rule prepare_gas_network in file /mnt/l/Git/Namibia/pypsa-earth-sec/Snakefile, line 148:
Job 25  completed successfully, but some output files are missing. Missing files after 5 seconds. This might be due to filesystem latency. If that is the case, consider to increase the wait time with --latency-wait:

Removing output files of failed job prepare_gas_network since they might be corrupted:

Personally, as mentioned in the PR, I'd recommend to keep the workflow consistent and keep the plotting functions as separate rules. What do all think about it? @energyLS @hazemakhalek @Eddy-JV

P.S. @doneachh I really recommend you to attend a meeting as we are discussing the merge and I believe it is relevant for you

@davide-f sounds like a good solution. Sadly i can not join today as i have another meeting at the same time, but keep me updated what the others say to this issue and I'll adjust this PR afterwards :)

Totally agree here, plotting/analysis should be separate.
