Shameless plug: Same for Javascript and without the links :-) https://www.jigdev.com

Any web equivalent of this? Wish it was a JS library so I could use it in my stuff!

This looks great! I've been looking for exactly something like this for one of my side projects: https://weblight.vercel.app/I'll dig in a bit later/tomorrow, but assuming I'll be able to run some of my own JS to convert the code into the visual representation. If not you might have a pull request soon :)

Looks like bling.js https://gist.github.com/paulirish/12fb951a8b893a454b32
