"Design a clean, minimalist map inspired by the London Underground, with only a few color-coded lines, each representing a literary genre (e.g., fiction, non-fiction, fantasy, science fiction). Keep the number of stations limited and use simple, clear typography for station names, which are famous book titles or authors. Avoid excessive detail and use only subtle, small icons near each station (like a book or quill) to hint at the genre. The overall design should be simple, with bold, easy-to-follow lines and vibrant but balanced colors." --ar 16:9  --s 750
