Introduction to LangGraph

Welcome to this next part of our journey, where you’ll learn how to build applications using the LangGraph
framework designed to help you structure and orchestrate complex LLM workflows.
LangGraph
is a framework that allows you to build production-ready applications by giving you control tools over the flow of your agent.
