## 📝 Notes

1. **Optional Dependencies**: The application works with or without optional dependencies (TextBlob, spaCy, Matplotlib, NumPy, Twilio, Firebase). Missing packages are detected and the application degrades gracefully.

2. **API Keys**: Some features require API keys (OpenWeatherMap required, OpenAI optional). The application handles missing keys gracefully.

3. **One Call API**: Weather alerts feature requires OpenWeatherMap One Call API subscription. The application handles this gracefully.

4. **Database**: Defaults to SQLite but supports PostgreSQL and MySQL. All database operations are safe.

5. **Error Handling**: Comprehensive error handling at all levels - API calls, data processing, user input, etc.
