I wrote more about the motivation for Observable (formerly d3.express) last year: https://medium.com/@mbostock/a-better-way-to-code-2b1d2876a3... It’s easy to use D3 within Observable, but it’s not pre-loaded or specifically built-in. Any browser library published to npm can be loaded via require (for AMD) or dynamic import (for ES modules). I’ve published a bunch of notebooks with D3 but you’ll find other ones with…

Absolutely! We all quite like Python, and there's no denying that JavaScript doesn't have the same caliber and range of scientific code (yet!). I fully expect plenty of people to do some of the data-crunching in Python, Julia, R, and so on, and bring it into Observable to explore and experiment. And I also expect JavaScript's ecosystem to blossom, especially with WebAssembly & WebGL hitting the mainstream.

What’s the status of d3 ports to Python? I believe plotly, d3py, and Bokeh all offer some amount of support. I’d expect more python users to bring d3 in that bring python to JavaScript.

I would have loved something like this while learning to program as well. I mean ... the Ruby REPL was fun, but this sort of thing is just so much more tactile and visual. We haven't had time to produce as many demo notebooks as we might have liked, but these notebooks really aren't D3-specific in the slightest. They're a reactive flavor of JavaScript, and anything that produces a value or can be rendered to the DOM…

The sliders on https://beta.observablehq.com/@mbostock/clifford-attractor-i... don't work for me, the sliders don't move. If I double-click a cell and edit the value, I get an updated graphic, but the sliders won't move. Chrome 63.0.3239.132, OS X 10.13.3

Google colab allows to create Python notebooks and run them (directly on Google cloud) without paying anything, or setting anything up
