This fork of the D3 v5 Zoomable Sunburst visualizes hierarchical data as an interactive radial partition layout. Clicking a node zooms the view to focus on that node’s subtree, with smooth animated transitions between levels. The code uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute the layout, while `transition.attrTween` animates arc paths and labels. Data is loaded from the Observable `@observablehq/flare` dataset, rendered as SVG paths with color-coded top-level branches and interactive click handlers.

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

Fork of D3 v5 Zoomable Sunburst

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 D3 v5 Zoomable Sunburst

This example visualizes a hierarchical dataset as a zoomable sunburst chart, where clicking a ring segment zooms in to show that subtree, with a central circle allowing navigation back to the root. The chart uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and render the radial layout, with smooth animated transitions driven by `transition.attrTween` and `d3.interpolate`. Data is loaded asynchronously from the `@observablehq/flare` package via the Observable stdlib.

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

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

This zoomable sunburst visualizes a hierarchical dataset representing the Flare visualization toolkit, using an SVG rendering with animated transitions powered by D3 v5. The visualization shows the hierarchical structure as a radial layout, with arcs partitioned by value and colored by top-level category. Clicking a node zooms in to expand that subtree, while clicking the center circle returns to the root. The code uses `d3.partition`, `d3.hierarchy`, `d3.arc`, and `transition.attrTween` to animate both the arcs and their labels, with data loaded from an Observable standard library module.

Fork of D3 v5 Zoomable Sunburst

This zoomable sunburst visualization displays a hierarchical dataset from the @observablehq/flare library. Clicking on an arc zooms into that subtree, with animated transitions between views. The code uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.interpolate` to compute the radial layout and smooth interpolation. It renders with SVG paths and text, using a rainbow color scale and `transition.attrTween` for the animation, all orchestrated via the Observablehq stdlib.

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

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.
