LangGraph for Beginners: Understanding State, Nodes, Edges & Graph Execution

In this video, I break down the core concepts you need to understand before building agentic workflows with LangGraph, including State, Nodes, Edges, and Graph execution. You’ll learn: ✔️ What a State is and how to define a state schema ✔️ How Nodes work and how they’re called during execution ✔️ How to pass and access state inside every node ✔️ What Edges are and how they determine execution flow ✔️ How to build simple and conditional graphs ✔️ How to think about agentic workflows using LangGraph We’ll build: 🔹 A simple graph with one node 🔹 A more advanced graph with three nodes and a conditional edge Whether you're new to LangGraph or trying to understand how agentic systems work, this tutorial will give you the foundation you need to start building powerful graph-based AI workflows.
