A zoomable sunburst visualization displays hierarchical data in a radial layout, with the root at the center and leaves along the circumference, where each arc’s angle and radius encode its value. Clicking an arc zooms into that subtree, and clicking the center circle zooms back out, using smooth animated transitions. The code employs the d3.layout.partition layout, d3.svg.arc for arc geometry, and d3.scale.linear and d3.scale.sqrt for positioning, with color from d3.scale.category20c. Data comes from the included flare.json file, and the zoom effect uses transition.attrTween to interpolate the domain and range scales.

AI-generated description

Click on any arc to zoom in. Click on the center circle to zoom out.

A sunburst is similar to a treemap, except it uses a radial layout. The root node of the tree is at the center, with leaves on the circumference. The area (or angle, depending on implementation) of each arc corresponds to its value. Sunburst design by John Stasko. Data courtesy Jeff Heer.

zoomable sunburst with sunlight colors

This zoomable sunburst diagram displays hierarchical data with arc labels, using the Flare dataset. Clicking an arc zooms into that subtree, the center circle zooms back out, and the background resets the view. The visualization uses D3 v4’s `d3.partition`, `d3.arc`, and `d3.scaleOrdinal` with a 30-color palette from the Sunlight Foundation Style Guide. Labels render along curved paths via `d3.path` and `textPath`, with animated transitions driven by `transition.attrTween` and interpolated scales. A white contour stroke improves label readability.

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.

Zoomable Sunburst

This zoomable sunburst chart displays the hierarchical file structure of the Flare visualization library, using a radial layout where the root node sits at the center and leaves occupy the circumference. Each arc's angle corresponds to its value, and the visualization uses a d3.layout.partition to compute the layout. Clicking an arc zooms in by reinterpolating the x and y scale domains and ranges over 750 milliseconds, while the d3.svg.arc component redraws the arcs via an attrTween on the path data. The color scale d3.scale.category20c assigns colors based on parent node names, and the data comes from a JSON file.

Zoomable Sunburst with Labels

This interactive sunburst chart displays hierarchical data with arc labels, allowing users to click any arc to zoom into that subtree, click the center circle to zoom out, or click the canvas to reset. The visualization uses a D3.js v4 partition layout with linear and square-root scales, rendering SVG paths and text elements. It employs `d3.hierarchy`, `d3.arc`, and animated transitions via `transition.attrTween`, while labels are positioned along the arcs using `textPath` elements. The data comes from a JSON file of the Flare dataset, and text is hidden when it does not fit within an arc segment.

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.

Zoomable Sunburst with Labels

This zoomable sunburst chart uses D3.js (v3) to visualize hierarchical data from flare.json, with each arc sized by value and colored by parent category. The visualization features smooth animated transitions that zoom between hierarchy levels when clicking on arcs, with labels displayed for each node. Built with SVG rendering, the chart encodes the flare dataset's multi-level structure, allowing users to explore the relationships between top-level categories and their nested children through interactive zooming and a clean, labeled sunburst layout.

D3 v5 Zoomable Sunburst

This interactive sunburst visualization displays a hierarchical dataset from the Observable “flare” library. The circular treemap partitions data by category and subcategory, with each arc’s size reflecting the value. Clicking an arc smoothly zooms to that node, re-centering the layout and fading out unrelated segments, using `d3.hierarchy`, `d3.partition`, and `d3.arc` for geometry and `transition.attrTween` for animation. The SVG output is styled with `d3.scaleOrdinal` and `d3.interpolateRainbow` for color, while labels and tooltips are generated via D3 selections.
