This interactive sunburst visualizes hierarchical data from the Observable `@observablehq/flare` dataset, showing the flare library’s package structure with color-coded arcs and labels. Clicking a node zooms into that subtree with a smooth 750ms transition, adjusting arc positions and label rotations via `d3.transition` and `tween` interpolation. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, `d3.arc`, and a sequential `d3.scaleOrdinal` with interpolated rainbow colors. The SVG renders all nodes, hiding non-visible arcs and labels through opacity filters.

Fork of Fork of Fork of D3 v5 Zoomable Sunburst

This zoomable sunburst visualizes the hierarchical flare dataset, showing nested categories as concentric arcs whose angular width encodes value. Clicking an arc zooms into that subtree with a smooth 750ms transition, while a central circle returns to the root. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute layout and geometry, with `transition.attrTween` animating arc paths and label rotations. The data loads from the `@observablehq/flare` module via the Observable runtime and renders as SVG with a rainbow color scale.

Fork of D3 v5 Zoomable Sunburst

A fork of the D3 v5 Zoomable Sunburst example, this visualization shows the hierarchical structure of the Flare dataset as an interactive, animated sunburst diagram. Clicking a node zooms into that branch, smoothly transitioning arcs and labels via `d3.transition` and `transition.attrTween`. It partitions the data with `d3.hierarchy`, `d3.partition`, and `d3.arc`, and colors arcs using `d3.scaleOrdinal` with a rainbow interpolator. The example loads data from the `@observablehq/flare` package, rendering with SVG in an HTML page.

Fork of D3 v5 Zoomable Sunburst v1

This interactive sunburst diagram visualizes a hierarchical dataset through nested, color-coded arcs that zoom and pan with click interactions. Built with D3 v5, it uses `d3.hierarchy` and `d3.partition` to compute layout, while `d3.arc` generates each segment. Transitions animate via `transition.attrTween` and interpolated arc paths, with labels rotating and fading based on visibility criteria. The data originates from the `@observablehq/flare` package, rendered as SVG with responsive scaling.

Fork of D3 v5 Zoomable Sunburst

This interactive sunburst chart visualizes hierarchical data from the Observable Flare dataset, with each arc representing a node and its size proportional to its value. Users click on arcs to zoom into that subtree, triggering a smooth 750ms animation that repositions and rescales all visible elements. The visualization is built with D3 v5, using `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute the layout, while color encoding is derived from a rainbow interpolator applied to top-level branches. Transitions employ `transition.attrTween` with an interpolator to animate arc paths and labels during zoom interactions.

Fork of Fork of D3 v5 Zoomable Sunburst

This visualization presents a zoomable sunburst of the Flare dataset, showing a hierarchical file structure as multi-level arcs. Rendered with SVG and animated transitions, users click any segment to make it the new root, smoothly redrawing the tree with D3 v5’s updated partition layout. The code uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute geometry, while `transition.attrTween` and `d3.interpolate` animate the arcs and labels. Colors derive from `d3.scaleOrdinal` with an interpolated rainbow range, and the data loads asynchronously from the Observable Flare library.

Fork of D3 v5 Zoomable Sunburst

This sunburst visualization displays the hierarchical structure of the Flare data set, with each arc representing a node and its size proportional to the node’s value. Clicking an arc zooms in to show that node’s children, while clicking the center circle returns to the previous level. The visualization uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` APIs, with smooth transitions animated via `transition.attrTween`. Color is assigned using `d3.scaleOrdinal` with a rainbow palette, and the SVG is rendered from the `flare.json` data file.

Fork of D3 v5 Zoomable Sunburst

This interactive sunburst visualization displays the hierarchical flare dataset, using arc segments sized by value and colored by top-level category. Clicking a segment zooms into that subtree, with smooth animated transitions reshaping all arcs and labels. Built with D3 v5, the example uses `d3.hierarchy`, `d3.partition`, `d3.arc`, and `d3.interpolate` to drive the SVG rendering and 750ms transition animations. The data is loaded via the Observable standard library's `require` function.

Fork of D3 v5 Zoomable Sunburst

This interactive sunburst chart visualizes hierarchical data from the `@observablehq/flare` dataset, showing nested categories as colored arcs that can be clicked to zoom into sub-hierarchies. Built with D3 v5 and rendered as SVG, the visualization uses `d3.partition`, `d3.hierarchy`, and `d3.arc` to compute layout geometry, with `d3.scaleOrdinal` and `d3.interpolateRainbow` for color mapping. Clicking an arc triggers a smooth 750ms transition via `transition.attrTween` that interpolates angular and radial coordinates, while labels rotate and fade based on visibility thresholds. Ancestor tooltips appear via appended `title` elements.
