## Overview

This repository appears to be a Java demo project exploring AI workflows: creating naive and model-based embeddings, searching vectors, using vector stores, and connecting language models to an AI service and RAG. The filenames identify these capabilities, but no README or source excerpts were provided. Consequently, the graph preserves the apparent product areas without asserting a workflow order, calls, data transfers, or external integrations that cannot be verified from the available evidence.
