A zoomable sunburst visualizes the hierarchical structure of the Flare dataset, with arcs sized by value and colored by top-level category. Clicking a node animates a zoom to that branch of the hierarchy. The visualization uses D3 v5’s `d3.partition`, `d3.hierarchy`, and `d3.arc` to compute layout and paths, with `transition.attrTween` for smooth animated updates. Data originates from the `@observablehq/flare` module, rendered as SVG with rotating labels.

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 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

This zoomable sunburst chart visualizes the hierarchical Flare dataset, showing the size of each node through arc length and color-coded by top-level category. Clicking an arc zooms into that subtree, recomputing the partition layout and animating the transition. Built with D3 v5, it uses `d3.partition`, `d3.hierarchy`, `d3.arc`, and `transition.attrTween` to smoothly interpolate arc geometry and label positions. The visualization renders as SVG with interactive animations, and data is loaded asynchronously from the Observable `@observablehq/flare` module.

D3 v5 Zoomable Sunburst

This visualization renders the Flare software package hierarchy as a zoomable sunburst, where each arc segment represents a node and its size encodes the node’s value. Users can click arcs or the central circle to drill down or back up through the hierarchy, with animated transitions handled by `d3.transition` and `transition.attrTween`. The code uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and draw the layout in SVG, while `d3.scaleOrdinal` with `d3.interpolateRainbow` assigns colors to top-level branches. The data is loaded asynchronously from the `@observablehq/flare` module via the Observable standard library.

D3 v5 Zoomable Sunburst

This interactive sunburst visualization displays the hierarchical structure of the Flare dataset, with arc size proportional to leaf-node values and color encoding by top-level category. Clicking any arc zooms to that subtree via animated transitions using `d3.transition` and `transition.attrTween`, while an inner circle returns to the root. Built with D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc`, labels rotate to remain readable. Data loads through the Observable standard library’s `require()` method, and rendering uses SVG with `fill-opacity` to indicate parent-child relationships.

D3 v5 Zoomable Sunburst

This zoomable sunburst diagram visualizes the hierarchical structure of the Flare dataset, with nested arcs representing categories and subcategories. Clicking a node smoothly zooms and re-centers the view on that segment, while fading out irrelevant arcs and labels. Built with D3 v5, it uses `d3.partition`, `d3.hierarchy`, and `d3.arc` to compute the layout, and `transition.attrTween` for animated interpolation between states. Data loads via the Observable standard library, with SVG rendering and a rainbow color scale for top-level branches.

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.

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.
