This visualization displays a zoomable sunburst chart of the Flare data hierarchy, using D3 v5 and the Observable standard library. The chart presents hierarchical data as concentric arcs, with the root node at the center and children radiating outward. Users can click on any segment to zoom into that level, which smoothly animates the transition to show the selected branch in detail. The code employs D3's `d3.partition`, `d3.arc`, `d3.hierarchy`, and `d3.interpolate` functions, combined with `transition.attrTween` for animated updates. Each segment is color-coded by its top-level category, and labels appear for sufficiently sized arcs.

Fork of D3 v5 Zoomable Sunburst

A zoomable sunburst chart visualizes the hierarchical structure of the Flare dataset, with arcs color-coded by top-level category and sized by value. Clicking a segment rotates and scales the visualization to focus on that subtree, using D3 v5 transitions and `transition.attrTween` to animate arc geometry and label positions. The chart renders with SVG, leveraging `d3.hierarchy`, `d3.partition`, and `d3.arc`, while loading data asynchronously via the Observable standard library and `require`.

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

A zoomable sunburst chart displays the hierarchical structure of the Flare dataset as a radial layout, with each ring segment representing a category and its subcategories. The visualization animates transitions when a user clicks a segment, zooming into that node and its descendants while keeping the surrounding context visible. Built with D3 v5, the chart uses `d3.hierarchy`, `d3.partition`, and a custom `d3.arc` generator to compute the geometry, while `transition.attrTween` smoothly interpolates the arc paths and label transforms during the 750ms zoom animation. The dataset is loaded from an Observable library and rendered as an SVG.

Fork of D3 v5 Zoomable Sunburst

This zoomable sunburst chart visualizes the hierarchical structure of the Flare data set, showing the relative sizes of data categories and subcategories through radial arcs. Built with D3 v5, the visualization uses the `d3.hierarchy` and `d3.partition` APIs to compute the sunburst layout, while the `d3.arc` generator draws the segments. The code loads data via `observablehq` and `require()`, and implements interactive zooming through click handlers that trigger a 750ms transition, using `transition.attrTween` to animate both the arc paths and labels as the view reorients around the selected node.

Fork of D3 v5 Zoomable Sunburst

This zoomable sunburst chart visualizes the hierarchical flare dataset, where each ring segment represents a category and its size reflects the summed value of its children. Clicking an arc smoothly zooms into that node, re-scaling the partition layout and labels. Built with D3 v5, it uses `d3.partition`, `d3.hierarchy`, `d3.arc`, and `d3.interpolate` within a `transition.attrTween` animation, rendering as SVG with zoom transitions triggered by click events. The flare data is loaded via the Observable standard library’s `require` method.

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.

This interactive sunburst chart visualizes the hierarchical structure of the Flare dataset, showing relative sizes of categories and subcategories as concentric arcs. Users click any segment to zoom into that branch, with smooth 750ms transitions animating the radial layout. Built with D3 v5, the visualization uses `d3.partition` for layout, `d3.arc` for path generation, and `d3.interpolateRainbow` for color coding. SVG rendering with `transition.attrTween` smoothly updates arc geometry and label positions during zoom interactions.

Fork of D3 v5 Zoomable Sunburst

This zoomable sunburst visualizes a hierarchical dataset representing the Flare visualization toolkit, using an SVG rendering with animated transitions powered by D3 v5. The visualization shows the hierarchical structure as a radial layout, with arcs partitioned by value and colored by top-level category. Clicking a node zooms in to expand that subtree, while clicking the center circle returns to the root. The code uses `d3.partition`, `d3.hierarchy`, `d3.arc`, and `transition.attrTween` to animate both the arcs and their labels, with data loaded from an Observable standard library module.
