Smart Travel Planner / Voyage.ai

We are group09-Smart Travel Planner doing an website called Voyage.ai which is a smart travel planning web app prototype. Users can enter trip details such as destination, dates, travelers, and budget. The React frontend sends the trip request to a Node.js/Express backend, and the backend returns a sample itinerary.
