Generative AI for images and music produce pixels and waveform data, respectively. I wonder if there is research into "procedural" data; so in this case, it would be SVG elements and, perhaps, MIDI data respectively. I know training data would be much more harder to get, (notwithstanding legal ramifications), but I think that creating structured, procedural data will be much more interesting than just the final, "raw" output!
