That colourblind palette is golden, thank you for sharing it. And I was just talking about me wanting have a crack at creating that arrow myself, but thank you for offering to share. I'll be sure to reach out if I find myself being unable to replicate it.

I wasn't even talking about tikzplotlib. It's just that pgf backend is now supported by matplotlib and you can produce pgf files with:

 python

    
import matplotlib.pyplot as plt
import matplotlib

matplotlib.use('pgf')

fig, ax = plt.subplots()
# Code related to plotting here

fig.savefig("outputfile.pgf")


  

with relevant rcParams options in matplotlibrc, then import the pgf with:

 latex

    
\begin{figure}[h]
    \centering
      \resizebox{\linewidth}{!}{
        \input{outputfile.pgf}
      }
    \caption{Caption here.}
\end{figure}

  

But Python -> CSV -> LaTeX/pgf pipeline is quite smooth, for sure. I understand why you'd decide to opt for it without involving too many third-party dependencies.
