Some similar work: https://www.willusher.io/webgl-volume-raycaster/#Hydrogen%20... , though caveat, that while labeled "Hydrogen Atom", the density shown is of just one state of the electron; http://phelafel.technion.ac.il/~orcohen/DFTVisualize.html .

There are many more visualizations that show total electron density rather than individual states. Though arguably far far too few, given how pervasively unsuccessfully these topics are taught.

If you'd like to explore, GPAW https://wiki.fysik.dtu.dk/gpaw/ can be useful. Here's a random example of use: https://www.brown.edu/Departments/Engineering/Labs/Peterson/...
