This zoomable sunburst visualizes the hierarchical structure of the Flare software package, with each ring segment representing a directory or file and its area proportional to a numeric value. It uses D3 v5’s `d3.partition` layout and `d3.arc` generator to draw SVG arcs, with click interactions and smooth transitions (`transition.attrTween`) that recenter and rescale the hierarchy. A color scale from `d3.interpolateRainbow` distinguishes top-level categories, while labels rotate and fade based on visibility. Data loads asynchronously via the Observable standard library’s `require` function.

Mike Bostock's D3 Zoomable Sunburst example

<br></br> Ported from this Observable notebook for this forum thread. Many thanks to Bryan Gingechen who answered my question about the necessary steps to get from an (Observable) JavaScript notebook to a vanilla JavaScript index.html. He presented his solution on blockbuilder.org

D3 v5 Zoomable Sunburst

This interactive visualization displays the hierarchical structure of the Flare data as a sunburst diagram, partitioned into concentric rings where each ring represents a level of the hierarchy and arc angles encode numeric values. Clicking a segment zooms the view to focus on that subtree, using animated transitions that smoothly rescale and reposition arcs via `d3.interpolate` and `d3.attrTween`, with colors assigned by `d3.scaleOrdinal` and `d3.interpolateRainbow`. Rendered as SVG with D3 v5, it loads hierarchical JSON data and relies on the Observable stdlib’s `d3.partition` and `d3.arc` generators, adapting Bostock’s original example for vanilla JavaScript.

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.

D3 v5 Zoomable Sunburst

This zoomable sunburst visualizes the hierarchical structure of the Flare dataset, displaying nested arcs whose size and color encode node values and category. Users click any arc to zoom into that subtree, with smooth 750-millisecond transitions animating arc paths and labels via `d3.transition` and `transition.attrTween`. The code uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and render the SVG layout, while a rainbow color scale distinguishes top-level branches. Data loads asynchronously from the Observable Flare module using `observablehq/stdlib`.

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.

D3 v5 Zoomable Sunburst

This interactive sunburst diagram visualizes the hierarchical structure of the Flare dataset, where each ring segment represents a category and its size corresponds to its value. Users click a segment to zoom into that branch, re-centering the visualization and smoothly animating the arcs and labels. Built with D3 v5, the example uses `d3.hierarchy`, `d3.partition`, and a custom `d3.arc` to compute geometry, while `transition.attrTween` animates the changing path data. The color scheme assigns hues to top-level categories using `d3.scaleOrdinal` and `d3.interpolateRainbow`.

D3 v5 Zoomable Sunburst

This zoomable sunburst chart visualizes the hierarchical structure of the Flare data library, using D3 v5’s `d3.arc`, `d3.partition`, and `d3.hierarchy` APIs. The root hierarchy is loaded via an ObservableHQ library (`@observablehq/stdlib`), and each ring segment is colored by top-level category with proportional arc lengths. Clicking a node smoothly zooms the chart via `transition.attrTween` and `d3.interpolate`, animating both arc geometry and label rotation. The SVG rendering includes hover tooltips showing the full path and numeric value for each leaf.

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

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.
