Test it

Using "claude-d3js-skill". Create a line chart showing monthly temperature trends

Expected outcome:

A complete D3.js React component with SVG line chart, including x-axis (months), y-axis (temperature), smooth curve interpolation, gradient fill area under the line, and tooltip showing exact values on hover.

Using "claude-d3js-skill". Build a pie chart for market share comparison

Expected outcome:

An interactive D3.js pie chart with animated entry transitions, separated slices on hover, percentage labels, external legend with colour coding, and click-to-explode selected slice animation.

Security Audit

Safe

v1 • 2/25/2026

All 392 static analyzer findings were evaluated and dismissed as false positives. The pattern detections for 'external_commands', 'weak cryptographic algorithm', 'C2 keywords', 'network', and 'filesystem' operations were triggered by markdown documentation code blocks, D3.js API method names (schemeCategory10, nodes, desc), hex color codes in colour scheme documentation, and standard CDN import examples. This is a legitimate D3.js data visualization skill containing only documentation and code templates with no executable security risks.

What You Can Build

Business Dashboard Developer

Create executive dashboards with KPI charts, trend visualisations, and interactive filters for business analytics platforms.

Data Journalist

Build engaging, interactive stories with custom charts and maps that help readers explore data-driven narratives.

Research Analyst

Generate publication-quality scientific visualisations with precise control over scales, axes, and statistical representations.

Try These Prompts

Basic Bar Chart

Create a responsive bar chart using D3.js that displays quarterly revenue data. Include proper axis labels, tooltips on hover, and use a colour-blind accessible palette. Provide the complete React component code.

Interactive Scatter Plot

Build an interactive scatter plot with D3.js where each point represents a product. Add zoom and pan functionality, click-to-highlight individual points, and a legend that updates dynamically when data filters change.

Force-Directed Network Graph

Create a force-directed network diagram showing relationships between entities. Implement node dragging, collision detection, custom link styling based on relationship type, and animated transitions when nodes are added or removed.

Choropleth Map with Drill-Down

Build a geographic choropleth map using D3.js geo projections. Display regional data with colour encoding, add zoom transitions between country and state levels, and show tooltips with detailed statistics on hover.

Best Practices

Always clear previous SVG content with selectAll('*').remove() before re-rendering to prevent duplicate elements
Use margin convention for proper axis spacing and accommodate label overflow in chart dimensions
Implement responsive sizing with ResizeObserver or window resize listeners for adaptive layouts

Avoid

Do not hardcode dimensions - always use responsive containers that adapt to parent element size
Avoid creating scales inside loops or transitions - define them once and reuse for performance
Never use D3 for simple static charts - prefer CSS or lightweight libraries for basic visualisations

Frequently Asked Questions

Can I use this skill with frameworks other than React?

Yes. D3.js works with any JavaScript environment including Vue, Svelte, Angular, and vanilla JavaScript. The skill provides integration patterns for each framework.

Does D3.js require a backend or server?

No. D3.js is a client-side library that runs entirely in the browser. You provide the data (as JSON, CSV, or other formats) and D3 handles the visualisation.

What is the difference between D3.js and chart libraries like Chart.js?

D3.js provides low-level building blocks for custom visualisations with complete control, while chart libraries offer pre-built chart types with simpler APIs but limited customisation.

How do I handle real-time data updates?

Use D3's data join pattern with the .join() method or manual enter-update-exit selection pattern. The skill provides templates for animated transitions when data changes.

Can I export D3.js visualisations as images?

Yes. Convert the SVG to a canvas element and use canvas.toDataURL() to generate PNG or JPEG exports. The skill can provide implementation guidance for this workflow.

Is D3.js suitable for mobile devices?

Yes, but consider performance. Use touch events for interactions, simplify visualisations for smaller screens, and implement progressive rendering for large datasets.
