Canvas as a background

[arunoruto]

It is only possible to set a static image as the background. A GIF would be possible, too, but this is more dynamic than a procedural-generated JavaScript background. I was toying around with p5js and created a script that generates topographic contour maps: https://editor.p5js.org/souleater45/full/IU5ZoAsp6

I am certainly one of many who want such dynamic images as their background on the front (or maybe as an article background). How difficult would it be to implement such a solution? Could you let me know if there is a need for such a solution? This isn't something a shortcode would solve, but for my needs, a div with the appropriate styling needs to be created to host the canvas (the rest should be done by the js script, like putting the canvas inside the div and so on). I don't know if this applies to d3 or other libraries.
