# 🎉 Canvas Highlighting API - Community Showcase

Welcome back to Noodl! After over a year of waiting, we're excited to show you what we've been building.

## Quick Start

1. **Open the Noodl editor** and load a component with nodes
2. **Open DevTools**: View → Toggle Developer Tools
3. **Run the demo** by pasting this in the console:

```javascript
noodlShowcase.start();
```

Sit back and watch the magic! ✨

## What You'll See

The demo showcases the new **Canvas Highlighting API** with:

- **🌊 Four Channels**: Lineage (blue), Impact (orange), Selection (white), Warning (red)
- **🌊 Wave Effect**: Rainbow cascade through your nodes
- **🎆 Grand Finale**: All nodes pulsing in synchronized harmony

## Manual API Usage

After the demo, try the API yourself:

```javascript
// Highlight specific nodes
HighlightManager.instance.highlightNodes(['node-id-1', 'node-id-2'], {
  channel: 'lineage',
  color: '#4A90D9',
  style: 'glow',
  label: 'My Highlight'
});

// Clear all highlights
HighlightManager.instance.clearAll();

// Or clear just the showcase
noodlShowcase.clear();
```

## API Features

### Channels

- `lineage` - Data flow traces (blue glow)
- `impact` - Change impact analysis (orange pulse)
- `selection` - Temporary selection states (white solid)
- `warning` - Errors and warnings (red pulse)

### Styles

- `glow` - Soft animated glow
- `pulse` - Pulsing attention-grabber
- `solid` - Clean, static outline

### Multi-Channel Support

Multiple highlights can coexist on different channels without interference!

## What's Next?

This API is the foundation for powerful new features coming to Noodl:

- **📊 Data Lineage Viewer** - Trace data flow through your app
- **💥 Impact Radar** - See what changes when you edit a node
- **🔍 Component X-Ray** - Visualize component hierarchies
- **🐛 Trigger Chain Debugger** - Debug event cascades
