Auto Graph Generation - Implementation Summary

✅ Completed

I've successfully implemented a comprehensive auto-layout and graph generation system for Redstring. Here's what was built:

🏗️ Architecture

Core Services (New Files)

1. src/services/graphLayoutService.js (340 lines)

  • Five layout algorithms:
    • Force-Directed: Fruchterman-Reingold physics simulation with spring forces and repulsion
    • Hierarchical: BFS-based tree layout with level detection
    • Radial: Concentric orbit layout around most-connected node
    • Grid: Regular rows and columns
    • Circular: Equal spacing on circle perimeter
  • Configurable parameters for each algorithm
  • Respects Redstring's instance-based architecture

2. src/services/autoGraphGenerator.js (550 lines)

  • Input parsers:
    • Simple JSON (nodes + edges format)
    • JSON-LD / RDF (semantic web format with @context)
    • Auto-detection based on structure
  • Intelligent prototype management:
    • Searches for existing prototypes by name
    • Reuses prototypes for semantic consistency
    • Creates new prototypes only when needed
  • Instance creation with layout positions
  • Edge creation with proper directionality
  • Four sample data templates:
    • Simple Network (5 nodes)
    • Family Tree (hierarchical, 6 nodes)
    • Knowledge Graph (JSON-LD, 4 nodes)
    • Concept Network (dense, 7 nodes)

UI Components (New Files)

3. src/components/AutoGraphModal.jsx (240 lines)

  • Modal dialog with full configuration UI:
    • Data source selector (Sample / Custom)
    • Sample template dropdown
    • Custom JSON input textarea
    • Format selector (Auto / Simple JSON / JSON-LD)
    • Layout algorithm dropdown (5 options)
    • Target mode (Add to Current / New Graph / Replace)
    • Graph name input (for new graphs)
  • Input validation
  • Live sample preview with stats

4. src/components/AutoGraphModal.css (250 lines)

  • Maroon-themed styling matching Redstring aesthetic
  • Responsive layout with scrollable content
  • Form controls with proper focus states
  • Button groups and radio buttons
  • Monospace textarea for JSON input

🔧 Integration Points (Modified Files)

1. src/RedstringMenu.jsx

  • Added "Generate Test Graph" menu item in Debug menu
  • Menu item triggers modal open via callback
  • Styled with teal color (#4ecdc4) for debug features
  • Positioned after "Show Debug Overlay" before settings

2. src/Header.jsx

  • Added onGenerateTestGraph prop
  • Passes handler through to RedstringMenu

3. src/NodeCanvas.jsx

  • Imported AutoGraphModal and generation services
  • Added modal state (autoGraphModalVisible)
  • Added handler to open modal (onGenerateTestGraph)
  • Integrated generation logic with store actions:
    • Parses input data
    • Generates graph with selected options
    • Shows results notification
    • Handles errors gracefully
  • Modal positioned at end of component tree with other modals

📊 Key Features

Prototype Intelligence

  • Reuse over Create: Searches existing prototypes by name before creating new ones
  • Semantic Consistency: Maintains single source of truth for concepts
  • Type Preservation: Respects typeNodeId relationships

Layout Quality

  • Collision Avoidance: All algorithms prevent node overlap
  • Bounds Management: Keeps nodes within canvas with configurable padding
  • Configurable Spacing: Adjust distances, forces, iterations per algorithm
  • Centering: Prevents graph drift in force-directed layout

Data Format Support

  • Simple JSON: Easy to write, human-readable
  • JSON-LD: Full semantic web compatibility with RDF
  • URI Preservation: Maintains @id references for linked data
  • Property Mapping: Intelligently maps various property names (name/label/rdfs:label)

User Experience

  • Sample Templates: Quick testing without writing JSON
  • Live Preview: Shows node/edge counts for samples
  • Mode Selection: New graph, add to current, or replace
  • Error Handling: Graceful failures with clear error messages
  • Results Notification: Summary of what was created

🎯 Usage Flow

  1. User clicks Redstring Menu → Debug → Generate Test Graph
  2. Modal opens with configuration options
  3. User selects:
    • Sample data or pastes custom JSON
    • Layout algorithm
    • Target graph mode
  4. User clicks "Generate Graph"
  5. System:
    • Parses input data
    • Finds/creates prototypes
    • Applies layout algorithm
    • Creates instances with positions
    • Creates edges
    • Shows results
  6. Graph is immediately visible on canvas

📝 Documentation

Created comprehensive guide: AUTO_LAYOUT_GUIDE.md

  • Feature overview
  • Input format specifications
  • Layout algorithm details
  • Architecture explanation (three-layer system)
  • API documentation
  • Configuration options
  • Sample data examples
  • Best practices
  • Troubleshooting guide

✨ Respects Redstring Architecture

Three-Layer System

  1. Prototypes: Reusable semantic concepts (shared across universe)
  2. Instances: Positioned occurrences in graphs
  3. Graphs: Spatial contexts containing instances

Store Integration

  • Uses storeActions.addNodePrototype() for new concepts
  • Uses storeActions.addNodeInstance() with positions
  • Uses storeActions.addEdge() for connections
  • Uses storeActions.createNewGraph() when requested
  • Properly manages Maps and Sets

Edge Format

  • Respects dual format (instance IDs + prototype metadata)
  • Creates proper directionality objects
  • Sets appropriate typeNodeId for relations

🧪 Testing Ready

Ready to test with:

  1. Sample templates (built-in, 4 options)
  2. Custom JSON (paste your own)
  3. JSON-LD import (RDF/semantic web data)
  4. All 5 layout algorithms
  5. Different graph modes (new/current/replace)

🚀 Next Steps for User

To test the feature:

  1. Start Redstring
  2. Click Redstring menu (top left)
  3. Debug → Generate Test Graph
  4. Try "Simple Network" with "Force-Directed" layout
  5. Click "Generate Graph"
  6. See immediate results on canvas!

To iterate on layouts:

  • Try different algorithms (hierarchical, radial, etc.)
  • Adjust layout parameters in code (spacing, iterations)
  • Test with your own data (paste custom JSON)

To extend:

  • Add new layout algorithms in graphLayoutService.js
  • Add new sample templates in autoGraphGenerator.js
  • Add new input parsers in parseInputData()
  • Customize layout parameters per algorithm

🎨 Visual Integration

  • Modal matches Redstring aesthetic (maroon theme)
  • Menu item uses debug color scheme (teal)
  • Results notification uses native alert (can be upgraded to toast)
  • No visual conflicts with existing UI
