This is also doable with one line of bash via imagemagick in any terminal that supports the Kitty or iTerm2 graphics protocols, which is most mainstream ones (iTerm2 itself, Kitty, Konsole, etc.)
I don't say this to bash your techniques but to point out that there are other methods which permit quick prototyping and easy iteration, and that LLMs are, at least in my experience, not a paradigm-shifting improvement in this vein.
