D3.js Interactive Data Exploration Skill

This skill allows you to build interactive dashboards and data exploration tools using D3.js. The goal is to facilitate user interaction with complex datasets, allowing them to filter, sort, and drill down into the data dynamically.

When to use

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

• "Create an interactive dashboard"
• "Enable filtering on my dataset"
• "Build a data exploration tool"
• "Allow users to drill down into data"
• "Visualize data with interactive features"

If the user requires static visualizations or reports, don’t use this skill—opt for the D3.js Visualization Skill instead.

---

Inputs you should expect

• One or more local data files: *.csv, *.tsv, *.json
• User interaction requirements:
  • Filter options (fields, conditions)
  • Sorting preferences
  • Drill-down paths (hierarchical structure)
  • Dimensions (width/height) for the dashboard
  • Any labeling requirements (titles, descriptions)
• Output constraints:
  • Interactivity level (e.g., "requires dynamic filtering" or "no interaction needed")

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/dashboard.html — standalone HTML that renders the interactive exploration tool
2. dist/dashboard.js — JavaScript file containing the interactivity logic (modular and reusable)
3. (Optional) dist/dashboard.css — if the task specifies custom styling for the dashboard

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

Interactivity guidelines (non-negotiable)

To ensure a smooth user experience:

Interaction rules

• Provide clear UI elements for filtering and sorting (e.g., dropdowns, sliders).
• Ensure that data updates dynamically based on user interactions without page refresh.
• Maintain consistent visual feedback (e.g., loading indicators when fetching new data).

Data loading considerations

• Use asynchronous data loading techniques (e.g., d3.json, d3.csv) to avoid blocking the UI.
• Implement error handling to manage data loading failures gracefully.

Example Usage

<!DOCTYPE html>
<html>
<head>
    <title>Interactive Data Dashboard</title>
    <link rel="stylesheet" href="dist/dashboard.css">
    <script src="https://d3js.org/d3.v6.min.js"></script>
    <script src="dist/dashboard.js"></script>
</head>
<body>
    <div id="dashboard">
        <h1>Data Exploration Dashboard</h1>
        <div id="filters"></div>
        <svg id="visualization"></svg>
    </div>
</body>
</html>

This example demonstrates the basic structure of an HTML file that uses the interactive data exploration tool. Adjust the #filters and #visualization elements based on your dataset and requirements.
