GraphRAG for Engineering Diagrams: ChatP&ID Enables LLM Interaction with P&IDs

ArXi:2603.22528v1 Announce Type: cross Large Language Models (LLMs) combined with Retrieval-Augmented Generation (RAG) and knowledge graphs offer new opportunities for interacting with engineering diagrams such as Piping and Instrumentation Diagrams (P&IDs). However, directly processing raw images or smart P&ID files with LLMs is often costly, inefficient, and prone to hallucinations. This work
