My complaint is really more that for this sort of thing I feel examples should be front and center; Jupyter "sells" a better experience, so show me how easy and ergonomic it is to use!
Hope that helps. Right now it looks like the sql parts are kind of the equivalent of running a subshell and displaying the results, with no communication to the "main" code. Is this accurate? Is there a way forward in the future to e.g. pull the data down with sql and then do some further munging in another language?
