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

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 interactive sunburst diagram displays the hierarchical flare dataset with zoomable partitions. Built with D3 v5, it uses d3.partition and d3.hierarchy to compute angular layout, with d3.arc rendering SVG paths. Clicking a slice zooms into that subtree via transition.attrTween, interpolating arc geometry and adjusting fill-opacity and label visibility. Labels rotate using SVG transforms, and the color scale uses d3.scaleOrdinal.

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.

D3 v5 Zoomable Sunburst

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.

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 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.

Fork of D3 v5 Zoomable Sunburst

This zoomable sunburst chart visualizes the hierarchical flare dataset using D3 v5. The visualization partitions data into a radial layout, with arcs representing nodes and their sizes proportional to values. Clicking an arc transitions the view to zoom into that node, re-scaling the partition layout and updating arc paths and labels. The code uses d3.hierarchy, d3.partition, and d3.arc for the layout and rendering, with d3.transition and attrTween animating the zoom. Colors are assigned via d3.scaleOrdinal with an interpolateRainbow range, and SVG text labels rotate and reposition dynamically.
