Thanks for making this :) As of now I just export Jupyter Notebooks to html, throw them on my site and call it a day but have been meaning to try Idyll for some data visualization.
Presumably you can switch between idyll and Jupiter notebooks using note down and nbconvert with a bit of extra work.
Well, I have already put some extra work in making jupyter notebooks look good when exported as html (for example - http://abhirag.in/articles/train_of_thought_1.html). I am planning to use Idyll for d3 plots and such, but thanks for the idea, exporting to markdown and then using Idyll was something I hadn't thought about.
Nice notebook more railways around the world should be using notebooks.
