+# SimpleAudit Visualization
+
+Visual tools for reviewing SimpleAudit results with an interactive web interface.
+
+## 📊 Two Ways to Visualize Results
+
+### Method 1: CLI Server (Recommended for Multiple Files)
+
+Start a local web server to browse and visualize multiple JSON result files from a directory.
+
+**Installation:**
+```bash
+pip install simpleaudit[visualize]
+```
+
+**Usage:**
+```bash
+# Visualize results from a specific directory
+simpleaudit serve --results_dir ./my_audit_results
+
+# Custom port and host
+simpleaudit serve --results_dir ./results --port 8080 --host 0.0.0.0
+```
+
+**Or run directly with uv (no installation needed):**
+```bash
+# Run directly using uvx
+uvx simpleaudit[visualize] serve --results_dir ./my_audit_results
+
+# With custom port and host
+uvx simpleaudit[visualize] serve --results_dir ./results --port 8080 --host 0.0.0.0
+```
+
+> **Note:** `uvx` requires `uv` to be installed on your system. Install it with:
+> ```bash
+> pip install uv
+> # or see https://docs.astral.sh/uv/getting-started/installation/
+> ```
+
+**Features:**
+- 📁 Browse nested folder structures
+- 🔍 File tree with JSON validation
+- 📱 Mobile responsive design
+- 🎨 Interactive scenario list and detail views
+- 📊 Statistics dashboard with severity breakdown
+- 🔄 Hot reload - just refresh to see updated files
+
+**Access:**
+Open your browser to `http://127.0.0.1:8000` (or your custom host/port)
+
+---
+
+### Method 2: Standalone Viewer (No Server Required)
+
+Open a single HTML file directly in your browser and upload JSON files.
+
+**How to use:**
+
+1. **Download the file:**
+   - Get `scenario_viewer.html` from `simpleaudit/visualization/`
+   - Or from: https://github.com/kelkalot/simpleaudit/blob/main/simpleaudit/visualization/scenario_viewer.html
+
+2. **Open in browser:**
+   - Double-click `scenario_viewer.html` or
+   - Right-click → Open with → Your browser
+
+3. **Upload your JSON:**
+   - Drag and drop your audit results JSON file
+   - Or click "Select File" to browse
+   - Try sample data to see how it works
+
+**Features:**
+- ✨ Works completely offline
+- 🔒 No data leaves your computer
+- 📤 Drag & drop JSON files
+- 🎯 Sample data included for demo
+- 📱 Mobile friendly
+- 🔄 Upload multiple files sequentially
+
+**Use cases:**
+- Quick one-off result review
+- Sharing results with stakeholders (single HTML file)
+- Offline environments
+- Privacy-sensitive data
+
+---
+
+## 📋 Supported JSON Formats
+
+Both visualization methods support these JSON structures:
+
+### Format 1: Array of Results
+```json
+[
+  {
+    "scenario_name": "Test Scenario",
+    "scenario_description": "Description here",
+    "score": 8.5,
+    "severity": "medium",
+    "history": [
+      {"role": "user", "content": "..."},
+      {"role": "assistant", "content": "..."}
+    ],
+    "reasoning": "Judge feedback..."
+  }
+]
+```
+
+### Format 2: Object with Results Array
+```json
+{
+  "timestamp": "2026-02-16T10:00:00Z",
+  "summary": {
+    "score": 8.5,
+    "total_scenarios": 10
+  },
+  "results": [
+    {
+      "scenario_name": "...",
+      "score": 8.5,
+      "severity": "medium",
+      ...
+    }
+  ]
+}
+```
+
+### Required Fields:
+- `scenario_name` or `name`: Scenario title
+- `scenario_description` or `description`: Brief description
+- `score`: Numeric score (0-10)
+- `severity`: One of: `pass`, `low`, `medium`, `high`, `critical`
+- `history` or `conversation`: Array of role/content pairs
+- `reasoning` or `feedback`: Judge evaluation text
+
+---
+
+## 🎨 Features
+
+### Statistics Dashboard
+- **Pass Rate**: Percentage of passing scenarios
+- **Average Score**: Overall score across all scenarios
+- **Severity Breakdown**: Visual bar chart of severity distribution
+
+### Scenario List
+- Color-coded severity indicators
+- Search by name or description
+- Sort by score or severity
+- Quick score preview
+
+### Detail View
+- Full conversation history with role badges
+- Comprehensive judge feedback
+- Severity tags and scores
+- Mobile-optimized back navigation
+
+### File Tree (CLI Server only)
+- Collapsible folder navigation  
+- JSON file validation
+- Nested directory support
+- Persistent selection state
+- Resizable sidebar (desktop)
+- Hide/show toggle
+
+---
+
+## 🚀 Examples
+
+### Example 1: Local Audit Results
+```bash
+# After running your audit
+simpleaudit serve --results_dir ./examples/local_audit_example_results
+```
+
+### Example 2: Multiple Audits
+```bash
+# Browse all audits in a directory
+simpleaudit serve --results_dir ./all_audits
+```
+
+### Example 3: Share with Team
+```bash
+# Start server on network-accessible host
+simpleaudit serve --results_dir ./results --host 0.0.0.0 --port 8080
+```
+
+Then share: `http://YOUR_IP:8080`
+
+### Example 4: Offline Review
+1. Download `scenario_viewer.html`
+2. Open in browser
+3. Upload your `audit_results.json`
+4. Review scenarios offline
+
+---
+
+## 🛠️ Customization
+
+### Custom Port
+If port 8000 is in use:
+```bash
+simpleaudit serve --results_dir ./results --port 8001
+```
+
+### Allow External Access
+To access from other devices on your network:
+```bash
+simpleaudit serve --results_dir ./results --host 0.0.0.0
+```
+
+---
+
+## 💡 Tips
+
+1. **File Organization**: Keep audit results in dated folders:
+   ```
+   results/
+   ├── 2026-02-01/
+   │   ├── model_a.json
+   │   └── model_b.json
+   └── 2026-02-15/
+       └── latest_audit.json
+   ```
+
+2. **Quick Checks**: Use standalone viewer for quick reviews of single files
+
+3. **Bulk Analysis**: Use CLI server when comparing multiple audit runs
+
+4. **Mobile Review**: Both methods work on mobile devices - use hamburger menu for navigation
+
+5. **File Validation**: Invalid JSON files won't appear in the file tree (CLI server)
+
+---
+
+## 🐛 Troubleshooting
+
+### Port Already in Use
+```bash
+# Error: Address already in use
+# Solution: Use a different port
+simpleaudit serve --results_dir ./results --port 8001
+```
+
+### No Files Showing
+- Ensure JSON files have `.json` extension
+- Check JSON is valid (use a validator)
+- Verify at least one file has `results` array
+
+### Standalone Viewer Not Loading
+- Make sure you're opening `scenario_viewer.html` (not `visualizer.html`)
+- Check browser console for errors
+- Try a different browser (Chrome, Firefox, Edge)
+
+### File Upload Not Working
+- Ensure you're uploading `.json` files
+- Check file size (very large files may be slow)
+- Verify JSON structure matches supported formats
