What is D3.js used for in Claude Code?

It provides low-level control to build highly customized, interactive visualizations that standard charting libraries like Chart.js cannot handle.

Can I use this for real-time data updates?

Absolutely. The skill includes a specific 'Update Visualization' workflow for refreshing charts with new data while maintaining object constancy and smooth transitions.

Does this skill support standard charts like bars and lines?

Yes, while it excels at complex designs, it includes workflows for building bar, line, and scatter plots from scratch using D3's scaling and axis generators.

When should I use D3 instead of Highcharts or Chart.js?

Use D3 when you need full design control, bespoke animations, or specialized layouts like treemaps, network graphs, and geographic projections that simpler libraries don't support.

What are the prerequisites for using this skill?

A basic understanding of JavaScript, SVG, and CSS is recommended, as D3 works by manipulating DOM elements directly based on data.

Data Science & ML

Builds custom, interactive data-driven visualizations using D3.js for complex layouts, maps, and bespoke charting requirements.

About

This skill provides comprehensive guidance for creating sophisticated data visualizations with D3.js, offering low-level control over SVG, HTML, and CSS. It empowers users to build everything from standard bar charts to complex force-directed graphs and geographic maps, ensuring high interactivity through data-binding, transitions, and zoom/pan capabilities. Ideal for scenarios where standard charting libraries lack the necessary flexibility, it focuses on the D3 core concepts like scales, axes, and the data-join pattern to transform raw data into insightful, animated visual experiences.

Key Features

Creation of complex layouts including networks, hierarchies, and geographic maps
Interactive features like zooming, panning, dragging, and brushing
Advanced scale transformation for mapping data to visual properties
Smooth animations and transitions for data-driven state changes
8 GitHub stars
Implementation of the D3 data-join pattern for dynamic DOM updates

Use Cases

Creating data-rich geographic visualizations and maps using custom projections
Developing complex network diagrams or relationship graphs with force simulations
Building bespoke interactive dashboards that require non-standard chart types
