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 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

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 and loadable Sunburst

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.

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 interactive sunburst visualization displays a hierarchical dataset from the Observable “flare” library. The circular treemap partitions data by category and subcategory, with each arc’s size reflecting the value. Clicking an arc smoothly zooms to that node, re-centering the layout and fading out unrelated segments, using `d3.hierarchy`, `d3.partition`, and `d3.arc` for geometry and `transition.attrTween` for animation. The SVG output is styled with `d3.scaleOrdinal` and `d3.interpolateRainbow` for color, while labels and tooltips are generated via D3 selections.

D3 v5 Zoomable Sunburst

This zoomable sunburst visualizes hierarchical data, showing the proportion of food categories across multiple cities. The data is loaded from the `@observablehq/flare` dataset and rendered as an SVG with animated transitions. Users can click on arcs or the central circle to zoom in and out. The code uses `d3.hierarchy`, `d3.partition`, `d3.arc`, and `d3.scaleOrdinal` with an interpolated rainbow color scheme, along with `transition.attrTween` for smooth updates.

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 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.
