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

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 interactive sunburst diagram visualizes the hierarchical structure of the Flare dataset, allowing users to click on any segment to zoom in and explore nested categories. Built with D3 v5, the visualization uses an arc partition layout with a radial layout, where the inner ring represents the root and outer rings show deeper levels. The code leverages `d3.partition`, `d3.hierarchy`, and `d3.arc` for geometry, and employs `d3.interpolateRainbow` for color coding. Animations are handled via `d3.transition` and `transition.attrTween`, smoothly interpolating arc positions and labels during zoom transitions.

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 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 visualizes hierarchical data from an Observable flare dataset, letting users click arcs to zoom into nested categories. Built with D3 v5, it renders the chart as an SVG using `d3.partition` and `d3.arc`, with animated transitions via `transition.attrTween` that smoothly interpolate arc positions. Colors derive from a rainbow scale based on top-level children, while labels dynamically appear or fade based on arc visibility. The example also includes a central reset circle to navigate back to the root.

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 structure of the Flare dataset, using colored arcs to represent categories and nested segments for subcategories. Clicking a segment smoothly zooms into that branch, animating the radial layout via `d3.transition` and `attrTween`. Rendered with SVG, it leverages `d3.partition`, `d3.hierarchy`, and `d3.arc` to compute the layout, while `d3.scaleOrdinal` and `d3.interpolateRainbow` drive the color scheme, with labels and tooltips (`<title>`) providing details on demand.
