# Knowledge graphs · Tech watch [Canonical source]() Representing entities and relationships to explore and retrieve context. ## [RAG-Anything: handling charts in multimodal documents]() RAG-Anything is a framework built on LightRAG for indexing and querying documents that mix text, images, tables, equations, and charts. It coordinates parsing and content analysis in a single multimodal pipeline. The project combines vector similarity with a knowledge graph, provides processors for different content types, and can pass retrieved images to a vision model during queries. A recent change also routes rendered charts through the image pipeline while preserving captions and extracted text. To update a previously indexed document, multimodal reprocessing must be explicitly enabled with `force_multimodal_reprocess=True`. 2026-10-29 · [Markdown]() · [Original resource]() ## [Build a knowledge graph for coding assistants with Graaph]() Graaph builds queryable graphs from code, docs, papers, and diagrams to give coding assistants more context.
