This zoomable sunburst chart visualizes hierarchical data from a flare.csv file, showing the relative sizes of data tables and their parent-child relationships. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to render the radial layout as SVG paths. Clicking a segment triggers an animated transition that re-centers the view, using `d3.interpolate` and `transition.attrTween` to smoothly morph the arcs and labels over 750 milliseconds, with color encoding and opacity distinguishing hierarchy levels.

<br></br> Ported from this Observable notebook for this forum thread. Many thanks to Bryan Gingechen who answered my question about the necessary steps to get from an (Observable) JavaScript notebook to a vanilla JavaScript index.html. He presented his solution on blockbuilder.org

D3 v5 Zoomable Sunburst

This zoomable sunburst chart displays hierarchical data as concentric arcs, where clicking a segment zooms in to show its children while the central circle returns to the root. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to render the SVG layout, with `transition.attrTween` animating arc positions and label transforms. The visualization loads the flare dataset via Observable’s stdlib and applies a rainbow color scale based on top-level categories.

D3 v5 Zoomable Sunburst

This zoomable sunburst chart visualizes hierarchical data from the flare dataset. Clicking a node zooms into that subtree, while a central circle returns to the parent level. The chart uses D3 v5’s `d3.partition` layout and `d3.hierarchy`, rendering arcs as SVG paths with `d3.arc`. Interactive transitions animate via `transition.attrTween`, updating arc geometry and label rotations with color scales from `d3.interpolateRainbow`.

D3 v5 Zoomable Sunburst

This zoomable sunburst visualizes hierarchical data from the flare library, displaying nested categories as concentric rings where arc size encodes value. Clicking a node zooms into that subtree, with smooth transitions animated via `d3.transition` and `transition.attrTween`. The chart is built with D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc`, using SVG rendering with rainbow color scales. Labels rotate and fade based on visible arc size, and a central circle returns to the root view.

D3 v5 Zoomable Sunburst

A zoomable sunburst chart displays hierarchical data as concentric arcs, where clicking a segment zooms in to show it as the new root. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and render the layout, with a color scale based on `d3.interpolateRainbow`. Clicking triggers a smooth 750ms transition via `transition.attrTween`, animating arc paths and labels. The hierarchy comes from the Observable `@observablehq/flare` dataset, rendered as SVG with interactive hover tooltips.

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 the hierarchical flare dataset, encoding each node’s value as the arc’s angular width. Clicking a slice zooms into that subtree, dynamically rescaling the partition layout and re-centering the view. Built with D3 v5 and SVG, the example uses `d3.partition`, `d3.hierarchy`, and `d3.interpolate` to animate transitions, reading hierarchical data from a CSV file with id and value fields. The rendered output includes a breadcrumb trail showing the current path.

D3 v5 Zoomable Sunburst

A zoomable sunburst chart displays hierarchical data from the flare.json dataset, showing nested categories as concentric arcs. Users click a segment to zoom into that branch, with smooth animated transitions. Built with D3 v5, the visualization uses SVG paths and the d3.partition layout, d3.arc for arc geometry, and d3.transition with attrTween to animate between states. Colors derive from a scaleOrdinal with an interpolateRainbow palette.
