complex-causal-analysis

Generates interactive D3.js Sankey-style causal network diagrams showing hierarchical cause-effect relationships with evidence and adjustable nodes.

An interactive causal network visualization skill for analyzing cause-and-effect relationships in complex systems. Creates beautiful D3.js-based Sankey-style diagrams showing how factors connect and propagate through systems.

Features

• Hierarchical Layout: Top-to-bottom flow from root causes to final outcomes
• Interactive Nodes: Click nodes to see details (causes, results, evidence)
• Draggable Elements: Drag any node to reposition; connections follow automatically
• Color-coded Strength: Green = strong (8-10), Yellow = medium (5-7) causal relationships
• Directional Arrows: Small arrows in the middle of each link showing causation direction
• Evidence Support: Each node can include historical or factual evidence
• Fixed Sidebar: Stays on screen while zooming/panning the graph
• Zoom & Pan: Mouse wheel to zoom, drag canvas to pan

Use Cases

• Historical event analysis (dynasty collapses, wars, revolutions)
• Business cause-and-effect mapping
• Scientific phenomenon chains
• Problem root cause analysis
• Decision tree visualization

Input Format

Provide JSON with this structure:

{
  "title": "Topic Name",
  "nodes": [
    { "id": "Node Name", "layer": 3, "type": "Category", "desc": "Description", "color": "#hex" }
  ],
  "links": [
    { "source": "Cause", "target": "Effect", "strength": 8 }
  ]
}

Layer Conventions

• Layer 3: Root causes / Deep factors
• Layer 2: Intermediate factors
• Layer 1: Direct causes
• Layer 0: Final outcomes

Strength Guidelines

• 8-10: Strong causal relationship
• 5-7: Medium causal relationship
• 1-4: Weak (exclude)

Example Prompt

Create a causal network visualization for [TOPIC].

Nodes:
- [list with id, layer, type, description]

Links:
- [list source → target with strength 1-10]

Requirements:
- Top-to-bottom layout
- Only medium (5-7) and strong (8-10) relationships
- Add small arrow in middle of each link
- Node details show causes and results
- Include evidence/support for each node

Output

Generates a standalone HTML file with:

• Embedded D3.js (via CDN)
• No external dependencies
• Works in any modern browser
• Mobile-responsive

Skill Activation

When you activate this skill, provide:

1. Your topic/theme
2. List of causal factors (nodes)
3. Relationships between factors (links)

The skill will generate the JSON and produce a clickable HTML file you can open in your browser.

Technical Details

• Built with D3.js v7
• Bezier curves for smooth link paths
• Force-directed initial positioning with manual adjustment
• SVG-based rendering for crisp graphics
• Dark theme with gradient background
