D3 v5 Zoomable Sunburst

D3 v5 Zoomable Sunburst

This interactive sunburst chart visualizes hierarchical data from the Flare dataset, representing the size of each node through the arc’s angular width and radial extent. Users click any arc to zoom into that subtree, with smooth 750-millisecond transitions applied via `transition.attrTween` and `d3.interpolate`. The visualization uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` to generate SVG paths and labels, with `d3.scaleOrdinal` and `d3.interpolateRainbow` providing color encoding. The Observable HQ standard library’s `require` method loads the data from the `@observablehq/flare` module.

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.

D3 v5 Zoomable Sunburst

This zoomable sunburst visualizes the hierarchical Flare dataset, showing the relative sizes of categories and subcategories as concentric arcs that expand and contract with animation on click. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute the layout, while transitions via `transition.attrTween` animate changes between zoom levels. Color is assigned using `d3.scaleOrdinal` with an interpolated rainbow palette, and the data is loaded asynchronously via the Observable `@observablehq/flare` module.

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 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 chart visualizes hierarchical data, displaying nested nodes as concentric arcs with color-coded categories and interactive labels. Clicking an arc zooms into that subtree, while clicking the center circle returns to the root. The visualization uses D3 v5’s `d3.partition` layout, `d3.arc` for path generation, and `d3.transition` with `attrTween` for smooth animated updates. Data is loaded from the `@observablehq/flare` dataset via the Observable stdlib, which the code fetches using `require()` before rendering the SVG.

D3 v5 Zoomable Sunburst

This interactive sunburst visualization displays the hierarchical Flare dataset as concentric arcs, with clickable parent nodes that smoothly zoom into deeper levels of the hierarchy. Built with D3 v5, it renders arcs using `d3.arc` and computes the layout with `d3.partition` on a hierarchy created by `d3.hierarchy`. Animations are driven by `transition.attrTween`, interpolating between arc positions with `d3.interpolate`, while labels fade and rotate using `labelTransform` based on visible arc bounds. The example loads the Flare JSON data via the Observable standard library's `require` function and uses a `d3.scaleOrdinal` with an interpolated rainbow palette.
