This interactive visualization displays a hierarchical sunburst chart of the Flare software package, with concentric rings representing nested categories and colored segments sized by node value. Clicking a segment animates the view to zoom into that node, expanding its children outward while receding other branches. Built with D3 v5, the example uses `d3.partition`, `d3.arc`, and `d3.hierarchy` to compute the layout, with smooth transitions driven by `transition.attrTween` and `d3.interpolate`. Data loads from the `@observablehq/flare` dataset.

D3 v5 Zoomable Sunburst

This interactive visualization presents a zoomable sunburst chart of the Flare data hierarchy, where clicking a ring segment smoothly transitions the view to that level. The chart encodes hierarchical relationships as concentric rings, with arc length proportional to values and colors assigned by top-level category. Built with D3 v5, it uses the `d3.partition()` layout, `d3.arc()` for path geometry, and CSS transitions driven by `transition.attrTween` to animate changes. The example loads data from the `@observablehq/flare` package and renders everything as SVG elements.

D3 v5 Zoomable Sunburst

This interactive sunburst diagram shows the hierarchical structure of the Flare dataset, with each ring segment representing a category and its value. Users can click on any segment to zoom in and focus on that branch, while clicking the central circle returns to the parent level. Built with D3 v5, the visualization uses `d3.hierarchy`, `d3.partition`, and animated SVG transitions to smoothly interpolate arc paths and labels via `transition.attrTween`. Data is loaded from the `@observablehq/flare` module, and colors are assigned using `d3.scaleOrdinal` with a quantized rainbow palette.

D3 v5 Zoomable Sunburst

This interactive sunburst chart visualizes the hierarchically structured Flare dataset, showing the relative sizes of data clusters and their nested subcategories through concentric arcs. Users click on any parent arc to zoom into that subtree and recenter the visualization, with smooth animated transitions handled by D3 transitions and `transition.attrTween`. The example is implemented in D3 v5, using `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and render the layout, while `d3.interpolateRainbow` provides a categorical color scale. Data loads via the Observable standard library from the `@observablehq/flare` module, and all elements are drawn as SVG paths and text labels.

D3 v5 Zoomable Sunburst

This interactive visualization displays a zoomable sunburst chart representing the hierarchical file structure of the Flare data. Using D3 v5's `d3.hierarchy` and `d3.partition`, the code computes the radial layout and renders it as SVG, with arcs colored by top-level category. Clicking a node triggers a 750ms animated transition via `g.transition()`, interpolating the arc geometry with `transition.attrTween`. The visualization loads the dataset through `observablehq.Library` from the `@observablehq/flare` module, with labels and arcs fading based on visibility thresholds.

D3 v5 Zoomable Sunburst

This interactive sunburst chart displays the hierarchical Flare dataset, where each ring segment represents a node and its angular width encodes the node's value. Clicking a segment zooms into that subtree, smoothly animating the layout using D3 v5’s `d3.partition`, `d3.hierarchy`, and `d3.arc` with `transition.attrTween` for interpolated arc paths. Labels and fill opacity update dynamically, while a central circle returns the view to the root. The visualization is rendered as SVG and uses `d3.scaleOrdinal` with an interpolated rainbow palette.

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.

D3 v5 Zoomable Sunburst

This zoomable sunburst visualizes the flare dataset, a hierarchical collection of file sizes. The visualization displays the hierarchy as concentric rings, where each ring segment represents a node, with size proportional to its value. Users click on a segment to re-center the view on that subtree, and click the central circle to zoom back out. Built with D3 v5, it uses `d3.hierarchy` and `d3.partition` for layout, and `d3.arc` for rendering paths. Interactions are animated via SVG `transition` and `attrTween` methods, with color mapping from `d3.scaleOrdinal` and `d3.interpolateRainbow`. The data is loaded from the `@observablehq/flare` dataset.

D3 v5 Zoomable Sunburst

This zoomable sunburst visualization displays the hierarchical Flare dataset, showing the relative sizes of categories and their subcomponents through concentric, color-coded arcs. Users can click on any segment to zoom into that branch, with animated transitions expanding and rotating the view around the central circle. The code uses D3 v5's `d3.hierarchy`, `d3.partition`, and custom `d3.arc` generators to draw SVG paths, while `transition.attrTween` and `d3.interpolate` handle the smooth geometric morphing between views. Data loads from the `@observablehq/flare` package via the Observable stdlib's `require` module.
