Great article/notebook! I just discovered Observable last week. I plan on using it a lot more. I have been a Mathematica user for years because of the notebook interface and curated data. Then came Jupyter notebooks. I still like Mathematica/Wolfram Alpha, and it's interface seems to have stood the test of time, but a collaborative notebook format online with a big community sounds awesome. Great explanation for me of t-SNEs. EDIT: I just saw the link to Stephen Wolfram's essay "What is a Computational Essay?" on the "Introduction to Notebooks" on Observable. No wonder!
