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

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 the hierarchical Flare dataset, showing relative sizes of its categories through nested arcs. Clicking a node smoothly zooms into its subtree, while a center circle returns to the root. The example uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute layout and shapes, with `transition.attrTween` and `d3.interpolate` animating arc positions. Labels rotate and fade based on visibility, and the color scale applies `d3.interpolateRainbow` per top-level branch, rendered as an SVG with user interaction.

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

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.

D3 v5 Zoomable Sunburst

The zoomable sunburst visualizes hierarchical data from the Observable Flare dataset as concentric arcs, where clicking a node recenters and rescales the view on that subtree. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` for layout and rendering, with smooth 750ms transitions driven by `transition.attrTween` and interpolation of arc geometry. Color is assigned per top-level branch via a rainbow ordinal scale, and labels rotate radially with visibility filtering.

D3 v5 Zoomable Sunburst

An interactive zoomable sunburst chart visualizes the hierarchical structure of the Flare data set. The radial layout partitions the root node into concentric rings, with arc segments representing each category and subcategory; the color of each leaf is inherited from its top-level group. Clicking on an arc zooms into that subtree, expanding its children while hiding others. Built with D3 v5, the visualization uses `d3.partition` for layout, `d3.arc` for path generation, and animated transitions via `transition.attrTween` to smoothly update arc shapes and labels.

D3 v5 Zoomable Sunburst

This zoomable sunburst visualizes the hierarchical flare dataset, showing nested categories as concentric arcs. Clicking a node smoothly zooms to focus on that subtree, with animated transitions of arc sizes and label positions. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to render SVG paths, while `d3.interpolate` and `transition.attrTween` animate the morphing geometry and opacity changes during navigation.
