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 - PD

This interactive zoomable sunburst visualization displays the hierarchical structure of the Flare dataset, with each ring segment sized by its value. Clicking an arc zooms into that node, using smooth animated transitions to refocus the layout. The code employs D3 v5’s `d3.hierarchy` and `d3.partition` for layout, `d3.arc` for path generation, and `transition.attrTween` to interpolate between states. Color is assigned via a rainbow scale, and labels rotate radially with `d3.interpolate`-based tweening. Data loads from the `@observablehq/flare` package through the Observable stdlib.

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 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.

D3 v5 Zoomable Sunburst

This zoomable sunburst visualization displays the hierarchical structure of the Flare dataset, showing parent-child relationships and relative sizes through concentric arcs. Built with D3 v5, it uses `d3.partition` to compute the layout, `d3.arc` for path generation, and `d3.scaleOrdinal` with an interpolated rainbow palette for coloring. Clicking any node triggers an animated transition via `transition.attrTween` and `transition.attr`, zooming to that subtree while labels adjust their rotation and opacity based on visibility thresholds. The dataset loads from the `@observablehq/flares` package, and all rendering is done in SVG.

D3 v5 Zoomable Sunburst

This interactive zoomable sunburst visualizes the hierarchical structure of the Flare dataset, where each ring segment represents a node and its size corresponds to a value. Users can click on any segment to zoom in, revealing its children and re-centering the view, or click the central circle to zoom back out. Built with D3 v5, the visualization uses SVG for rendering and employs animated transitions via `transition.attrTween` to smoothly interpolate arc paths and labels as the view changes. The hierarchical data is processed using `d3.hierarchy`, `d3.partition`, and `d3.arc`, with colors assigned via a quantized rainbow interpolator.

D3 v5 Zoomable Sunburst

The D3 v5 Zoomable Sunburst shows a hierarchical dataset of the Flare visualization library (loaded via the @observablehq/flare module) as a multi-ring sunburst chart. Clicking an arc zooms in to reveal its children, with smooth transitions applied to the arcs and labels via `transition.attrTween` and `d3.interpolate`. The visualization is rendered as SVG, uses `d3.hierarchy` and `d3.partition` for layout, and `d3.scaleOrdinal` with a rainbow palette for coloring top-level categories.

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 D3 v5 zoomable sunburst visualizes the hierarchical structure of the flare dataset, showing file sizes across categories and subcategories. The visualization uses a radial layout where each ring represents a level of the hierarchy, with arc lengths proportional to values. Clicking on any segment zooms in, while clicking the central circle returns to the root. The implementation leverages `d3.partition`, `d3.hierarchy`, and `d3.arc` to compute geometry, with transitions animated via `transition.attrTween`. Color encoding uses `d3.scaleOrdinal` with interpolated rainbow colors based on top-level category names.
