I don't many code but I have just used this one for a little funny image process https://p5js.org
but nothing to do with the Node Editor :)
Don't know if it's that you want! (a Web Tool editor... :)
https://editor.p5js.org/Pilou/sketches/y1GHaBqyT no need to be registered for launch it!
Launch it and just Drag & Drop an PNG image with a transparent background (maxi 1024*512)
the funny of that is you can modify anything you want in the code itself! (at your own risks :D
https://i.postimg.cc/Jh33d6C2/pmoi.png here a simple transparent PNG with a Moi objects if you have not one under the hands! :)
You must obtain something like this except Size and color :)
Following with a simple Moi object
of course result depends of your start image! :)
