+**Advanced RAG System with Role-Based Access Control, Visualizations, and Enhanced Security**
+
+A production-ready RAG (Retrieval-Augmented Generation) system for FinSolve Technologies featuring advanced RBAC enforcement, interactive visualizations, and comprehensive security measures.
+
+## 🌟 **Enhanced Features**
+
+### 🛡️ **1. RBAC Enforcement Layer**
+- **Retrieval-level filtering**: Role-based access enforced BEFORE document retrieval
+- **Intent classification**: Zero-shot query classification to validate access permissions
+- **Metadata-based filtering**: Documents tagged with role permissions for secure access
+
+### 💬 **2. Reference Attribution & Source Tracking**
+- **Document titles and types** clearly displayed (e.g., "Q4 Financial Report (Financial Document)")
+- **Source provenance**: Every response includes traceable document references
+- **Metadata enrichment**: Enhanced document information for better context
+
+### 🔐 **3. Unauthorized Query Handling**
+- **Graceful policy messages**: Clear explanations when access is denied
+- **Role-specific guidance**: Suggests appropriate alternatives based on user permissions
+- **Security logging**: Tracks unauthorized access attempts for audit purposes
+
+### 📈 **4. Enhanced Output Modalities**
+- **Interactive Charts**: Plotly visualizations for financial and marketing metrics
+- **Data Tables**: HTML tables with financial/marketing performance data
+- **Rich Formatting**: Structured responses with emojis and clear sections
+- **Multi-modal responses**: Text + Charts + Tables in single responses
+
+### 🔄 **5. Feedback Mechanism**
+- **5-star rating system**: User feedback on response quality
+- **Feedback storage**: Persistent feedback collection for system improvement
+- **Response analytics**: Track user satisfaction and system performance
+
+### 🧪 **6. Demo Role Switch Mode**
+- **Live role switching**: Switch between roles during demo presentations
+- **Stakeholder demos**: Perfect for showing different access levels
+- **Visual indicators**: Clear marking of demo vs. actual role usage
+
+### 🧠 **7. Zero-shot Intent Detection**
+- **Keyword-based classification**: Intelligent query categorization
+- **Domain validation**: Ensures users only access their permitted domains
+- **Multi-intent handling**: Sophisticated query understanding
+

+## 🎯 **Advanced Use Cases**
+
+### **Executive Dashboards**
+- **C-Level users** get comprehensive visualizations
+- **Financial metrics** with interactive charts
+- **Performance trends** across all departments
+
+### **Department-Specific Analytics**
+- **Finance**: Revenue charts, cost analysis tables, ROI metrics
+- **Marketing**: Campaign performance, customer acquisition trends

+
+## 🛠️ **Technical Enhancements**
+
+### **Advanced RBAC Implementation**
+```python
+# RBAC enforced at retrieval level
+def _enforce_rbac_at_retrieval(self, query: str, role: str):
+    query_intent = self._classify_query_intent(query)
+    
+    # Validate role permissions for query intent
+    if query_intent not in allowed_domains[role]:
+        return [], False  # Unauthorized access blocked
+    
+    # Filter documents by role before retrieval
+    role_docs = self.role_index.get(role, [])
+    return self._get_relevant_documents(query, role_docs), True
+```
+
+### **Interactive Visualizations**
+```python
+# Dynamic chart generation
+def _create_visualization(self, metrics: Dict, query_intent: str):
+    if query_intent == "finance":
+        fig = px.bar(x=quarters, y=revenues, title="Revenue Trends")
+        return fig.to_html(include_plotlyjs='cdn')
+```
+
+### **Enhanced Response Generation**
+```python
+# Multi-modal response with sources
+response, sources, visualization, table = self.enhanced_rag_system.query(
+    query, user_role
+)
+```
+
+## 📊 **Sample Enhanced Queries**
+
+### **Finance Team**
+- *"Show me Q4 revenue with charts"* → Text response + Revenue chart + Financial metrics table
+- *"What are our major cost drivers?"* → Cost analysis + Expense breakdown table
+- *"Create financial dashboard"* → Multiple visualizations + Key metrics
+
+### **Marketing Team**
+- *"Show customer acquisition trends"* → Trend analysis + Interactive line chart
+- *"Campaign performance with ROI"* → Performance data + Campaign comparison table
+- *"Create marketing metrics dashboard"* → Multi-chart dashboard
+
+### **Unauthorized Queries**
+- **HR user asking for financial data** → Graceful denial message with alternative suggestions
+- **Employee accessing engineering docs** → Clear access restriction with policy explanation
+
