This interactive sunburst chart visualizes a hierarchical taxonomy, allowing users to click on any arc to zoom into that branch and explore its nested categories. Each ring segment represents a node, with size encoding the accumulated value of its descendants. Built with D3 v5, the visualization uses `d3.partition`, `d3.hierarchy`, and `d3.arc` to compute and draw the layout, while a `transition.attrTween` smoothly animates the arcs and labels during zoom transitions. The SVG rendering and color scales are applied directly through D3 selections.

D3 v5 Zoomable Sunburst

This zoomable sunburst visualizes hierarchical data from the flare library, displaying nested categories as concentric rings where arc size encodes value. Clicking a node zooms into that subtree, with smooth transitions animated via `d3.transition` and `transition.attrTween`. The chart is built with D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc`, using SVG rendering with rainbow color scales. Labels rotate and fade based on visible arc size, and a central circle returns to the root view.

D3 v5 Zoomable Sunburst

This D3 v5 zoomable sunburst visualizes a hierarchical dataset, where clicking on a ring segment zooms in to reveal that branch as the new root. The visualization uses a radial partition layout, with arc segments representing nodes and their sizes proportional to values. Implemented with D3’s `d3.hierarchy`, `d3.partition`, and `d3.arc` APIs, it renders as an interactive SVG with smooth 750-millisecond transitions. Node colors derive from a quantized rainbow scale, and labels rotate along the arcs, with click handlers on parent circles enabling navigation. The data originates from the Observable “flare” library, which is loaded asynchronously.

D3 v5 Zoomable Sunburst

A hierarchical sunburst chart displays hierarchical data as concentric rings of arcs, with colors assigned to top-level branches. Clicking a segment smoothly zooms and re-centers the visualization on that arc, expanding its children outward while fading unrelated elements. Built with D3 v5, it loads data via the Observable standard library and uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and render the layout as SVG. Interactive transitions rely on `transition.attrTween` and `d3.interpolate` to animate arc positions and label rotations.

D3 v5 Zoomable Sunburst

This interactive zoomable sunburst displays hierarchical data from a JSON file, showing nested categories and values. The visualization updates its arcs and labels with smooth, 750-millisecond transitions, allowing users to click any arc to zoom in and focus on a sub-branch. Built with D3 v5, it uses the `d3.partition` layout, `d3.arc` for geometry, and `d3.scaleOrdinal` with `d3.interpolateRainbow` for color coding. The code employs `transition.attrTween` for animated path and label updates, with SVG rendering and hover tooltips showing the full path and value.

D3 v5 Zoomable Sunburst

This zoomable sunburst chart displays hierarchical data as concentric arcs, where clicking a segment zooms in to show its children while the central circle returns to the root. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to render the SVG layout, with `transition.attrTween` animating arc positions and label transforms. The visualization loads the flare dataset via Observable’s stdlib and applies a rainbow color scale based on top-level categories.

D3 v5 Zoomable Sunburst

This zoomable sunburst chart visualizes hierarchical data from the flare dataset. Clicking a node zooms into that subtree, while a central circle returns to the parent level. The chart uses D3 v5’s `d3.partition` layout and `d3.hierarchy`, rendering arcs as SVG paths with `d3.arc`. Interactive transitions animate via `transition.attrTween`, updating arc geometry and label rotations with color scales from `d3.interpolateRainbow`.
