Spherical Voronoi diagrams and Delaunay triangulation computed on the globe rather than a flat plane.

Modular chart components on D3 where axes, plots and layout are separate objects you compose into custom chart types.

Static site generator for data apps where build-time data loaders precompute snapshots so dashboards load instantly.

Tool for hand-placing curved swoopy annotation arrows on D3 charts and exporting the resulting coordinates.

React dataviz framework built around annotation, network and ordinal frames rather than chart-type presets.

Layout plugin that computes non-overlapping beeswarm arrangements for one-dimensional distributions, so every individual data point stays visible.

D3-based reusable chart library from Naver with a compact API, plugin system and unusually complete TypeScript definitions.

Fork of d3-force extending velocity-Verlet simulation to one, two or three dimensions.

Drop-in replacement for d3-force using random vertex sampling for linear-time layouts on large graphs.

Free-form lasso selection for D3 charts, letting users draw around points to filter scatterplots.

Vue 3 chart component library from Adyen built on D3 with a strict design-system-first component API.

Word cloud layout that places words with sprite-based collision detection, running asynchronously so it never blocks the page.

Constraint-based graph layout that supports alignment, non-overlap, flow direction and grouping constraints.

Extends d3-drag so globe rotation keeps spinning with momentum after the pointer is released.

Layout for loom diagrams, a chord-diagram variant that shows relationships between entities and a shared centre.

Scale that bins continuous data into discrete classes using k-means clustering rather than quantile or equal-interval breaks.

Path interpolator that handles transitions between paths with different numbers of points without visual jumping.

Layout algorithms for directed acyclic graphs — Sugiyama, zherebko and grid — as a d3-hierarchy-style module.

D3 plugin for horizon charts, a time-series encoding that stacks many metrics in a fraction of the vertical space.

Grammar-of-graphics chart library built around facets and declarative data mapping rather than per-chart-type config objects.

Renders a codebase as a force-directed flower where each file is a leaf sized by lines of code.

Time-based event series visualisation showing dense dot timelines per row, with zoom and brushing.

Convenience wrappers over D3 selections adding appendMany, translate, at/st shorthands and tspan wrapping.

Places labels inside stacked area bands at the largest fitting position, sized and rotated automatically.

Flame graph component for profiling and any hierarchical data, with search, zoom and differential comparison modes.

UpSet plot implementation for visualising intersections across many sets where Venn diagrams break down.

D3 plugin that generates sketchy backgrounds, hatched shapes and wobbly lines to give any D3 chart a drawn texture.

Time-data availability chart showing when each series has data and where the gaps are.

Annotation layer for D3 with badge, callout, curve and threshold annotation types plus draggable editing during design.

Legend generator for D3 colour, size and symbol scales that stays in sync with the scale it was built from.

Map projections that place distant territories such as Alaska, Hawaii and French overseas regions next to the mainland.

Skill that teaches Claude to build correct, idiomatic d3.js data visualisations instead of generic charting library output.

Component set for financial and technical charts on D3 that renders identical series to SVG, Canvas or WebGL from one definition.

Generates correct scale bars for projected geospatial data, accounting for distortion at the bar's location.

D3 module that generates SVG pattern fills — lines, circles, paths — for encoding categories without relying on colour alone.

D3 plugin for stock and financial charts with candlestick, OHLC, trendline and crosshair components.

React chart library with unusually strong defaults for radial, sankey, treemap and calendar heatmap types plus built-in motion.

Data-driven 3D charts rendering to X3D/X3DOM, covering 3D bar, scatter, surface and bubble charts.
