💬 LangGraph Multi-Agent Chatbot with Azure OpenAI (GPT-4o)

This project demonstrates a multi-agent chatbot system built using LangGraph, LangChain, and Azure OpenAI GPT-4o. It enables intelligent routing of user queries to specialized agents that can handle:

• 📦 Product Q&A (e.g., laptop features, specifications)
• 📑 Order Management (e.g., order status, updates)
• 💬 Small Talk (greetings, goodbyes)

The chatbot is designed to operate inside Google Colab, using userdata for secure credential handling and modular notebooks for agent logic.
