🎨 RuVector Graph Explorer UI

Interactive web-based visualization for exploring vector embeddings as a force-directed graph.

✨ Features

• 🌐 Interactive force-directed graph with D3.js
• 🖱️ Drag, zoom, and pan controls
• 🔍 Search and filter nodes by metadata
• 🎯 Similarity queries - click to find similar nodes
• 📊 Metadata panel with detailed node information
• ⚡ Real-time updates via WebSocket
• 📸 Export as PNG or SVG
• 📱 Responsive design for mobile devices
• 🎨 Color-coded nodes by category
• 📈 Live statistics dashboard

🚀 Quick Start

Installation

npm install ruvector-extensions express ws

Basic Usage

import { RuvectorCore } from 'ruvector-core';
import { startUIServer } from 'ruvector-extensions/ui-server';

// Initialize database
const db = new RuvectorCore({ dimension: 384 });

// Add some vectors
await db.add('doc1', embedding1, { label: 'Document 1', category: 'research' });
await db.add('doc2', embedding2, { label: 'Document 2', category: 'code' });

// Start UI server on port 3000
const server = await startUIServer(db, 3000);

// Open browser at http://localhost:3000

Run Example

npm run example:ui

Then navigate to http://localhost:3000 in your browser.

Main Interface

• Force-directed graph with interactive nodes
• Sidebar with search, filters, and statistics
• Real-time connection status indicator

Features Demo

1. Search: Type in search box to filter nodes
2. Select: Click any node to view metadata
3. Similarity: Click "Find Similar Nodes" or double-click
4. Export: Save visualization as PNG or SVG
5. Mobile: Fully responsive on all devices

🎮 Controls

Mouse/Touch

• Click node: Select and show metadata
• Double-click node: Find similar nodes
• Drag node: Reposition in graph
• Scroll/Pinch: Zoom in/out
• Drag background: Pan view

Buttons

• Search: Filter nodes by ID or metadata
• Similarity slider: Adjust threshold (0-1)
• Find Similar: Query similar nodes
• Export PNG/SVG: Save visualization
• Reset View: Return to default zoom
• Zoom +/-: Zoom controls
• Fit View: Auto-fit graph to window

WebSocket Events

Client → Server:

// Subscribe to updates
{ "type": "subscribe" }

// Request graph
{ "type": "request_graph", "maxNodes": 100 }

// Query similarity
{
  "type": "similarity_query",
  "nodeId": "node-123",
  "threshold": 0.5,
  "limit": 10
}

Server → Client:

// Graph data
{ "type": "graph_data", "payload": { "nodes": [...], "links": [...] }}

// Node added
{ "type": "node_added", "payload": { "id": "...", "metadata": {...} }}

// Similarity results
{ "type": "similarity_result", "payload": { "nodeId": "...", "similar": [...] }}

🎨 Customization

Node Colors

Customize in /src/ui/app.js:

getNodeColor(node) {
    const colors = {
        'research': '#667eea',
        'code': '#f093fb',
        'docs': '#4caf50',
        'test': '#ff9800'
    };
    return colors[node.metadata?.category] || '#667eea';
}

Styling

Edit /src/ui/styles.css:

:root {
    --primary-color: #667eea;
    --secondary-color: #764ba2;
    --accent-color: #f093fb;
}

Force Layout

Adjust physics in /src/ui/app.js:

this.simulation
    .force('link', d3.forceLink().distance(100))
    .force('charge', d3.forceManyBody().strength(-300))
    .force('collision', d3.forceCollide().radius(30));

🔧 Advanced Configuration

Custom Server

import { UIServer } from 'ruvector-extensions/ui-server';

const server = new UIServer(db, 3000);

// Custom middleware
server.app.use('/custom', customRouter);

await server.start();

Real-time Updates

// Notify clients of changes
server.notifyGraphUpdate();

// Broadcast custom event
server.broadcast({
    type: 'custom_event',
    payload: { data: 'value' }
});

📱 Mobile Support

The UI is fully optimized for mobile:

• ✅ Touch gestures (pinch to zoom)
• ✅ Responsive sidebar layout
• ✅ Simplified mobile controls
• ✅ Optimized performance

🚀 Performance

Large Graphs (1000+ nodes)

• Limit visible nodes to 500
• Use clustering for better performance
• Reduce force simulation iterations
• Hide labels at low zoom levels

Optimizations

// Reduce node limit
const maxNodes = 500;

// Faster convergence
this.simulation.alpha(0.5).alphaDecay(0.05);

// Conditional labels
label.style('display', d => zoom.scale() > 1.5 ? 'block' : 'none');

🐛 Troubleshooting

Graph not loading

• Check console for errors
• Verify database has data: GET /api/stats
• Check WebSocket connection status

Slow performance

• Reduce max nodes in sidebar
• Clear filters
• Check network tab for slow API calls

WebSocket issues

• Check firewall settings
• Verify port is accessible
• Look for server errors
