## Overview
This application demonstrates the power of CopilotKit working with an Agent Framework (LangGraph in this case), where the agent shares state with your React frontend, enabling seamless AI-human collaboration. Key features include:
- **Interactive Map** - Visualize your trips and places on a Leaflet-powered map
- **Google Maps Search** - The AI agent can search for real places using Google Maps API
- **Human-in-the-Loop** - Review and approve AI-suggested changes before they're applied
- **Shared State** - The AI agent and UI share the same state, keeping everything in sync
- **Smart Suggestions** - Context-aware chat suggestions based on your current trips
