I find it odd that Bostock doesn't even mention Jupyter notebooks in the introduction. It is by far the most common and popular interactive notebook and supports many languages. There is also a next version - Jupyter Lab[1] which looks fantastic!

I do like the design of the notebook and the ability to pin cells. I got tired of Jupyter's horrendous default interface and wrote a new interface skin called Spin Zero[2]. I am trying to convince the Jupyter community to pay attention to their design.
