    "## Overview\n",
    "\n",
    "This notebook provides a rigorous, side-by-side comparison of **Standard RAG (Vector-based)** and **GraphRAG (Graph-based)**, focusing on how GraphRAG creates a \"Chain of Evidence\" that Vector RAG cannot see.\n",

    "### The Challenge: Navigating Fragmentation\n",

    "In intelligence work, facts are scattered across reports. Vector search often fails to bridge \"semantic gaps\"—logical connections between entities that are not physically co-located in text. \n",

    "   - Cannot follow entity relationships\n",

    "   - Limited context expansion\n",
    "   - Fails on semantic gaps\n",

    "   - Bridges semantic gaps\n",

    "2. **GraphRAG Advantages**:\n",
    "   - Combines vector search with graph traversal\n",
    "   - Follows relationships to find connected information\n",
    "   - Bridges semantic gaps through graph structure\n",
    "   - Enables multi-hop reasoning (2+ hops)\n",
    "   - Provides \"Chain of Evidence\" for complex queries\n",
    "\n",
    "3. **When to Use Each**:\n",
    "   - **Vector RAG**: Simple fact retrieval, single-document queries, when relationships are not important\n",
    "   - **GraphRAG**: Complex multi-hop queries, relationship-heavy domains, when context expansion is needed\n",
    "\n",
    "### Conclusion\n",
    "\n",
    "GraphRAG creates a **\"Chain of Evidence\"** that Vector RAG cannot see by:\n",
    "- Traversing the knowledge graph structure\n",
    "- Following entity relationships across documents\n",
    "- Expanding context through graph connections\n",
    "- Enabling multi-hop reasoning for complex questions\n",
    "\n",
    "This makes GraphRAG particularly powerful for intelligence analysis, research, and any domain where understanding relationships is crucial.\n"
