This might also be a good place to explain the `import as` concept -- helpful especially when adding in several cells named 'chart'.

Thanks for the suggestion Aaron! We introduce 'as' in the next 'import' cell (a few cells down), which comes up at around 4:15 in the video. While I agree that this is a super helpful concept and we could introduce it in the very first import, we deliberately introduce the non-aliased syntax first to help learners get familiar with it. So for the sake of introducing the syntax gradually and of keeping this notebook in sync with the video, we'll leave it as it is for now. But thanks again for the suggestion, and for watching our videos!
