Build a Graph RAG System from Scratch

Description: In this hands-on video, you will build a complete Graph RAG system from scratch using LangChain, NetworkX, OpenAI, and ChromaDB, and then directly compare its outputs against the classic RAG system you built earlier. What you will build and learn: Building a knowledge graph using NetworkX from raw podcast data Integrating the knowledge graph with ChromaDB for hybrid retrieval Wiring the full Graph RAG pipeline with LangChain and OpenAI Running live queries and seeing real outputs on screen A split-screen comparison of RAG vs Graph RAG answers on the same queries Why Graph RAG g…
