Noob question: Import this into what? Into a Jupyter notebook? Into whatever my 'Observable notebook' is? I guess an Observable notebook JavaScript chunk? That seems to work, but maybe worth clarifying for noobz

What's this `r = ƒ(e)` doing here? I tried to have an Observable JS chunk with this and it throws ``` r = RuntimeError: e is not defined ```

Throws `cell = RuntimeError: chartGen is not defined` for me ``` cell = cellGen(tutorial_project) ``` Seems to be the fix (fix it here too)?

Thanks David! Can confirm, this error held me up for ages.
