I've used python for graphviz just because I wanted some looping for many-to-one or one-to-many relationships and the auto-complete that comes from anything with an LSP or Python mode. Honestly I'd use it just for the auto-complete. (Admittedly, I didn't look too hard for dedicated editing environments that could do it for DOT files specifically. I just wanted to make something real quick.)
