name: skill-107 description: Visualize complex network structures using D3.js (v6), enabling users to explore relationships and connections between data points.

D3.js Network Visualization Skill

Use this skill to create visual representations of network structures such as social networks, data relationships, or any interconnected systems using D3.js. The goal is to provide users with a visual insight into how different nodes are connected.

When to use

Activate this skill when the user asks for any of the following:

• "Visualize a network of relationships"
• "Create a social network graph"
• "Show connections between entities"
• "Map out a data relationship structure"

If the user requires more traditional data visualizations (e.g., charts, graphs), don’t use this skill—opt for the D3.js Visualization Skill instead.

Inputs you should expect

• One or more local data files: *.json or *.csv containing node and link data
• A network intent:
  • Node attributes (e.g., id, name, group)
  • Link attributes (e.g., source, target, relationship type)
  • Visualization preferences (e.g., layout type, force-directed graph)
• Output constraints:
  • Interactivity level (e.g., "hover to display details" or "click to expand nodes")

If details are missing, make reasonable defaults and document them in comments near the top of the output file.

---

Outputs you should produce

Prefer producing all of the following when feasible:

1. dist/network.html — standalone HTML that renders the network visualization
2. dist/network.svg — exported SVG representation of the network
3. (Optional) dist/network.json — if the task requires a data export of the network structure

Always keep outputs in a predictable folder (default: dist/), unless the task specifies paths.

Network visualization principles (non-negotiable)

To create effective network visualizations:

Layout considerations

• Use a force-directed layout for dynamic representations unless specified otherwise.
• Provide options for different layouts (e.g., radial, hierarchical) based on user needs.

Interactivity features

• Implement tooltips for nodes and links to display additional information on hover.
• Allow users to zoom and pan to explore dense network areas efficiently.

Example Usage

<!DOCTYPE html>
<html>
<head>
    <title>Network Visualization</title>
    <script src="https://d3js.org/d3.v6.min.js"></script>
    <script src="dist/network.js"></script>
</head>
<body>
    <h1>Network Graph</h1>
    <div id="network"></div>
</body>
</html>

This example demonstrates how to set up a simple HTML file to visualize a network. The network.js file would contain the logic for creating nodes and links and handling interactivity.
