"Generate a clean, modern, and minimalist subway-style map with no more than 4-5 simple, color-coded lines, each representing a book genre (e.g., fiction, non-fiction, fantasy). The stations should be famous book titles or authors, with clean, white backgrounds and clear, modern typography. Avoid vintage or old paper effects. The design should be simple, easy to follow, and emphasize clarity and readability. No excessive decoration or complex line interactions." --ar 16:9  --s 750
