# Quick Start: Testing Dagre Grid Layout
|
|
|
|
**Status**: ✅ Ready for Testing
|
|
**URL**: http://localhost:5173/uml-viewer
|
|
|
|
---
|
|
|
|
## How to Test (60 Seconds)
|
|
|
|
### 1. Open UML Viewer
|
|
```bash
|
|
# Dev server should already be running
|
|
# If not: cd frontend && npm run dev
|
|
|
|
# Open browser to:
|
|
http://localhost:5173/uml-viewer
|
|
```
|
|
|
|
### 2. Select a Diagram
|
|
- Click any diagram in the left sidebar
|
|
- Example: "Custodian Multi-Aspect (Mermaid Class)"
|
|
|
|
### 3. Try Force Layout (Default)
|
|
- You'll see scattered nodes (organic, physics-based)
|
|
- Nodes bounce around initially, then settle
|
|
- This is the original behavior
|
|
|
|
### 4. Switch to Grid Layout
|
|
- Click **[Grid]** button in toolbar (top-right area)
|
|
- Watch nodes snap into hierarchical grid
|
|
- Notice tight, organized arrangement
|
|
|
|
### 5. Switch Back to Force
|
|
- Click **[Force]** button in toolbar
|
|
- Watch nodes scatter organically
|
|
- Notice active button highlight (blue)
|
|
|
|
### 6. Test Persistence
|
|
- Refresh page (Cmd+R / Ctrl+R)
|
|
- Your layout preference should be remembered
|
|
|
|

|
|
|
|
## What to Look For
|
|
|
|
### ✅ **Grid Layout Should**:
|
|
- Arrange nodes in hierarchical rows/columns
|
|
- Point inheritance arrows top-to-bottom
|
|
- Use consistent spacing (80px horizontal, 120px vertical)
|
|
- Render instantly (no animation delay)
|
|
- Look similar to Mermaid diagrams
|
|
|
|
### ✅ **Force Layout Should**:
|
|
- Scatter nodes organically
|
|
- Animate for ~5 seconds before settling
|
|
- Keep nodes spread out (physics repulsion)
|
|
- Look like original D3 force simulation
|
|
|
|
### ✅ **Both Layouts Should**:
|
|
- Support zoom (mouse wheel / pinch)
|
|
- Support pan (click + drag background)
|
|
- Support node dragging (click + drag node)
|
|
- Export to PNG/SVG correctly
|
|
- Show active button highlight
|
|
|

## Troubleshooting
|
|
|
|
### Grid layout not showing?
|
|
- Check browser console for errors
|
|
- Try force layout first, then switch to grid
|
|
- Refresh page
|
|
|
|
### Buttons not working?
|
|
- Check that dagre is installed: `npm list dagre`
|
|
- Should show `dagre@0.8.5` or similar
|
|
|
|
### Layout preference not saving?
|
|
- Check localStorage in DevTools:
|
|
- Key: `uml-layout-type`
|
|
- Value: `"force"` or `"dagre"`
|
|
|
|
### TypeScript errors?
|
|
```bash
|
|
cd frontend
|
|
npx tsc --noEmit
|
|
```
|
|
|

## Quick Visual Test
|
|
|
|
**Expected Grid Layout** (Top-to-Bottom):
|
|
```
|
|
HeritageCustodian
|
|
↓
|
|
┌───────┴───────┐
|
|
↓ ↓
|
|
DutchHeritage Collection
|
|
Custodian
|
|
```
|
|
|
|
**Expected Force Layout** (Scattered):
|
|
```
|
|
HeritageCustodian
|
|
|
|
DutchHeritage Collection
|
|
Custodian
|
|
```

|
## Performance Benchmark
|
|
|
|
| Diagram Size | Force Layout | Dagre Grid |
|
|
|--------------|--------------|------------|
|
|
| 5 nodes | ~2 sec anim | Instant |
|
|
| 10 nodes | ~3 sec anim | Instant |
|
|
| 20 nodes | ~5 sec anim | Instant |
|
|
| 50+ nodes | ~10 sec anim | <1 sec |
|
|
|
|
**Recommendation**: Use Grid for most diagrams (faster, cleaner).

|
// Force layout switch
|
|
localStorage.setItem('uml-layout-type', 'dagre')
|
|
location.reload()
|
