# SDG Network Visualization - Analysis & Strategy

## Executive Summary

I've analyzed the existing SDG network modelling project and designed a **web-enhanced infinite loop system** that will progressively generate sophisticated force-directed network visualizations with automatic API discovery.

### What Was Reviewed

**Existing SDG Network Project** (`ai_docs/sdg-network-modelling/`):
- Python notebooks fetching UN SDG API data
- D3.js v3 force-directed graph visualization
- Basic network showing: Geographic areas ↔ Ecosystem Capitals ↔ SDGs ↔ Targets
- Simple interactions: hover tooltips, drag nodes
- Single API source (UN Statistics)

**Current Limitations:**
- Outdated D3.js version (v3 vs current v7)
- Single hardcoded API
- Basic visual design (simple circles/lines)
- Limited interactivity (just hover)
- No progressive enhancement
- No web learning integration

## New System Design

    group: "category",           // for color coding
    size: value,                 // visual size from data
    properties: {
        value: number,
        unit: "string",
        timestamp: "date",
        source_api: "api_name",
        // ... domain-specific attributes
    }
}
```

### Edge Structure
```javascript
{
    source: "node_id",
    target: "node_id",
    type: "relationship",        // correlation, dependency, etc.
    strength: value,             // for force simulation
    weight: value,               // visual width
    properties: {
        correlation: number,
        confidence: number,
        source_api: "api_name"
    }
}
```
