I think it would be crazy hard to do it in CLI but I am no expert and I would not mind if someone contradicts me :)
Once the .tex is written, it is not hard to produce a SVG from it. I use ImageMagick's convert CLI to convert from pdf to jpg, but we can also convert from pdf to svg. I put this example in ChatGPT (3.5, Web) and I am shocked how easily it can convert any AST I provide to him in TikZ. It does not get the sibling distance always right, but I did not asked him to. I would not be surprised if it could write me the converter AST->TikZ too 😅. I tried to use GraphViz too but it packs nodes with similar names, so I get a digraph and not a tree.
