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.

<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 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 `@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.

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 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 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 diagram visualizes the hierarchical Flare dataset, showing the relative sizes of its branches and leaves through concentric, angle-based arcs. Clicking an arc zooms in to display that node as the new root, with a smooth 750-millisecond transition animating the arcs and labels via `d3.arc` and `transition.attrTween`. The chart uses D3 v5's `d3.hierarchy`, `d3.partition`, `d3.scaleOrdinal`, and a quantized rainbow color scale, rendering as SVG. Labels rotate and flip to maintain readability, and center-clicking returns to the previous level.

Fork of D3 v5 Zoomable Sunburst

This interactive sunburst diagram visualizes the hierarchical Flare dataset, showing the relative sizes of categories and subcategories through radial arcs. Users can click on any arc to zoom into that portion of the hierarchy, with smooth animated transitions repositioning the layout. The visualization is built with D3 v5, using `d3.partition` to compute the layout, `d3.arc` for arc paths, and `transition.attrTween` to animate changes between states. Colors are assigned via `d3.scaleOrdinal` with an interpolated rainbow palette, and labels rotate to remain readable at various depths.

Fork of D3 v5 Zoomable Sunburst

This interactive sunburst visualization displays the hierarchical structure of the Flare dataset, where each arc segment represents a node and its angular width encodes the node's value. Clicking a segment zooms in to show that node as the new root, with smooth animated transitions updating arcs and labels. Built with D3 v5, the visualization uses `d3.hierarchy`, `d3.partition`, and `d3.arc` for layout, while `transition.attrTween` animates the changing arc paths during zoom. Color is assigned per top-level category using a rainbow scale.
