A zoomable sunburst chart visualizes the hierarchical flare dataset, with arcs sized by value and colored by top-level category. Clicking a node zooms to focus on that branch, while a central circle returns to the root. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` for geometry, with animated transitions via `transition.attrTween` and `d3.interpolate`. Labels rotate and fade based on arc visibility. Data loads asynchronously from the `@observablehq/flare` module.

Mike Bostock's D3 Zoomable Sunburst example

Sunburst

A zoomable sunburst chart visualizes the hierarchical flare dataset, showing nested categories as concentric rings where each arc's angular width represents its value. The visualization collapses or expands levels when a user clicks on an arc or the central circle, with smooth transitions animating the radial layout. Built with D3 v5, the code uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute the layout, while `transition.attrTween` and `d3.interpolate` animate arc geometry during zoom. The color scale uses `d3.scaleOrdinal` and `d3.interpolateRainbow`, and data loads asynchronously via the Observable `require` API.

D3 v5 Zoomable Sunburst

This interactive sunburst chart visualizes the hierarchically structured Flare dataset, showing the relative sizes of data clusters and their nested subcategories through concentric arcs. Users click on any parent arc to zoom into that subtree and recenter the visualization, with smooth animated transitions handled by D3 transitions and `transition.attrTween`. The example is implemented in D3 v5, using `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and render the layout, while `d3.interpolateRainbow` provides a categorical color scale. Data loads via the Observable standard library from the `@observablehq/flare` module, and all elements are drawn as SVG paths and text labels.

D3 v5 Zoomable Sunburst

A zoomable sunburst visualizes the hierarchical structure of the Flare dataset, with arcs sized by value and colored by top-level category. Clicking a node animates a zoom to that branch of the hierarchy. The visualization uses D3 v5’s `d3.partition`, `d3.hierarchy`, and `d3.arc` to compute layout and paths, with `transition.attrTween` for smooth animated updates. Data originates from the `@observablehq/flare` module, rendered as SVG with rotating labels.

D3 v5 Zoomable Sunburst

This interactive sunburst chart visualizes hierarchical data from the Flare dataset, representing the size of each node through the arc’s angular width and radial extent. Users click any arc to zoom into that subtree, with smooth 750-millisecond transitions applied via `transition.attrTween` and `d3.interpolate`. The visualization uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` to generate SVG paths and labels, with `d3.scaleOrdinal` and `d3.interpolateRainbow` providing color encoding. The Observable HQ standard library’s `require` method loads the data from the `@observablehq/flare` module.

D3 v5 Zoomable Sunburst

This zoomable sunburst chart visualizes hierarchical data, displaying nested nodes as concentric arcs with color-coded categories and interactive labels. Clicking an arc zooms into that subtree, while clicking the center circle returns to the root. The visualization uses D3 v5’s `d3.partition` layout, `d3.arc` for path generation, and `d3.transition` with `attrTween` for smooth animated updates. Data is loaded from the `@observablehq/flare` dataset via the Observable stdlib, which the code fetches using `require()` before rendering the SVG.

D3 v5 Zoomable Sunburst

This zoomable sunburst visualizes the hierarchical structure of the Flare dataset, displaying nested arcs whose size and color encode node values and category. Users click any arc to zoom into that subtree, with smooth 750-millisecond transitions animating arc paths and labels via `d3.transition` and `transition.attrTween`. The code uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and render the SVG layout, while a rainbow color scale distinguishes top-level branches. Data loads asynchronously from the Observable Flare module using `observablehq/stdlib`.

D3 v5 Zoomable Sunburst

This zoomable sunburst visualization displays the hierarchical Flare dataset, showing the relative sizes of categories and their subcomponents through concentric, color-coded arcs. Users can click on any segment to zoom into that branch, with animated transitions expanding and rotating the view around the central circle. The code uses D3 v5's `d3.hierarchy`, `d3.partition`, and custom `d3.arc` generators to draw SVG paths, while `transition.attrTween` and `d3.interpolate` handle the smooth geometric morphing between views. Data loads from the `@observablehq/flare` package via the Observable stdlib's `require` module.
