This interactive sunburst chart visualizes hierarchical data from the flare dataset, displaying restaurant categories and subcategories as concentric arcs. Clicking a segment zooms in to reveal that branch's children, while clicking the center circle navigates back up the hierarchy. Built with D3 v5, it uses custom partition layouts, arc interpolation, and CSS transitions to animate the zooming effect. The visualization loads data asynchronously via the Observable stdlib and renders everything as SVG with animated color and opacity changes.

<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

D3 v5 Zoomable Sunburst

A zoomable sunburst chart displays hierarchical data from the flare.json dataset, showing nested categories as concentric arcs. Users click a segment to zoom into that branch, with smooth animated transitions. Built with D3 v5, the visualization uses SVG paths and the d3.partition layout, d3.arc for arc geometry, and d3.transition with attrTween to animate between states. Colors derive from a scaleOrdinal with an interpolateRainbow palette.

D3 v5 Zoomable Sunburst

This interactive zoomable sunburst chart visualizes a hierarchical dataset of restaurant categories across multiple U.S. cities, with each ring segment representing a food type and its relative value. Users can click on any segment to re-center the visualization on that node, smoothly animating the repositioning and scaling of all arcs and labels over 750 milliseconds. Built with D3 v5, the implementation uses the `d3.hierarchy` and `d3.partition` APIs to compute the layout, `d3.arc` for rendering paths, and `d3.interpolate` within a `transition.attrTween` for seamless zoom transitions. Colors are assigned via a rainbow-interpolated ordinal scale, and the flare dataset is loaded asynchronously from the Observable stdlib.

D3 v5 Zoomable Sunburst

This zoomable sunburst chart visualizes hierarchical data, displaying restaurant categories (fast food, pizza, Mexican, etc.) across multiple cities, with each arc segment representing a portion of the total. The visualization uses D3 v5's hierarchical layout and partition functions to compute the arc geometry, rendering the sunburst as SVG paths with animated transitions. Clicking on a segment zooms into that subtree, using `d3.interpolate` and `transition.attrTween` to smoothly animate the arc angles and radii. The data originates from the Observable `@observablehq/flare` dataset, loaded dynamically via the Observable standard library's `require` function.

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 visualization displays a hierarchical dataset of restaurant categories across multiple cities, using concentric rings to represent nesting levels. Built with D3 v5, it renders as SVG with animated transitions triggered by clicking any arc to zoom into that subtree. The code loads data from the `@observablehq/flare` module and applies `d3.partition` with a radial layout, while `d3.arc` and `transition.attrTween` handle the smooth path interpolations between zoom states. Color is assigned via `d3.scaleOrdinal` with an interpolated rainbow palette.

D3 v5 Zoomable Sunburst

A zoomable sunburst visualization displays hierarchical data with a fictional dataset of restaurant categories across six North American cities. Users click arcs to zoom and transition between hierarchy levels, with smooth 750ms animated rotations and resizing. The example uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute the layout, with `transition.attrTween` handling the interpolation between view states. Labels and arc opacity dynamically adjust based on visibility. Data is loaded from the `@observablehq/flare` module via the Observable standard library in vanilla JavaScript.

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 chart visualizes the hierarchically structured Flare dataset, showing the relative sizes of data clusters and their nested subcategories through concentric arcs. Users click on any parent arc to zoom into that subtree and recenter the visualization, with smooth animated transitions handled by D3 transitions and `transition.attrTween`. The example is implemented in D3 v5, using `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and render the layout, while `d3.interpolateRainbow` provides a categorical color scale. Data loads via the Observable standard library from the `@observablehq/flare` module, and all elements are drawn as SVG paths and text labels.
