🎓 For Students (Project Presentation)

Before Presentation

1. Read QUICKSTART.md to set up
2. Test everything using TESTING_GUIDE.md
3. Review PROJECT_SUMMARY.md for highlights

During Presentation

1. Show Swagger UI (bonus points!) → http://localhost:8000/docs
2. Demo user journey:
   • Register → Login
   • Single prediction
   • Batch CSV with visualizations
3. Explain architecture using ARCHITECTURE.md

Key Points to Mention

✅ FastAPI with automatic API documentation
✅ JWT authentication for security
✅ RESTful API design
✅ Data visualization (Chart.js + WordCloud)
✅ Separation of concerns (clean architecture)
✅ Database relationships and ORM
