or through the provided Jupyter notebooks. The notebooks should already contain rendered figures, but you can re-run them as long as you set up a Python kernel (can be done using the provided requirements.txt file and a virtual environment).
Note: if the figures don't render on GitHub, you can use nbviewer to view the notebooks.
