Wow! This is insanely cool! You should package this up as a VS Code plugin so more people can use it. At a minimum, please post a license.txt file in your repo so folks can actually use it (MIT or similar is pretty easy and common for something like this, without a license.txt file it's not clear whether others can actually use it and many places that means they can't).
Hydrogen looks very cool! Am I right that hydrogen and the https://github.com/DonJayamanne/vscodeJupyter plugin that nojvek's plugin is designed to work with in that hydrogen shows the plots inline (like Jupyter does) but hydrogen doesn't support markdown? [edit: the biggest difference is that hydrogen is a stand-alone atom-like editor not a vscode plugin]
