This interactive sunburst diagram visualizes the hierarchical structure of the Flare dataset, with each ring segment representing a node whose angular width and radial extent encode its value. Clicking any segment smoothly zooms and re-centers the view on that subtree, with labels and arc opacity transitioning via `transition.attrTween` and `d3.interpolate`. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and render the SVG paths, while a custom color scale maps top-level categories to a rainbow palette.

Fork of D3 v5 Zoomable Sunburst

This interactive sunburst visualization displays the hierarchical structure of the Flare dataset, with each ring segment sized by value. Clicking a node zooms in to reveal its children, while the central circle returns to the root view. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, `d3.arc`, and animated transitions via `transition.attrTween` to smoothly interpolate arc positions. Colors derive from a `d3.scaleOrdinal` over the rainbow palette, and labels rotate with their arcs.

Fork of D3 v5 Zoomable Sunburst

This interactive sunburst diagram visualizes the hierarchical structure of the Flare dataset, using concentric rings to represent nested categories and their relative sizes. Clicking any arc zooms into that subsection, smoothly animating the layout through D3 transitions. The visualization is built with D3 v5, using `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and render the arcs as SVG paths. Colors are assigned via `d3.scaleOrdinal` with an interpolated rainbow palette, and labels rotate and fade based on the current zoom level.

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.

Fork of D3 v5 Zoomable Sunburst

This interactive sunburst diagram visualizes the hierarchical structure of the Flare software library, with each ring representing a level of the codebase and arc size proportional to data values. The D3 v5 code uses the `d3.partition` layout algorithm, `d3.arc` for drawing segments, and animated transitions triggered by clicking on any visible arc to zoom into the selected branch. SVG paths and text labels render in the browser, with colors assigned via `d3.scaleOrdinal` and an interpolated rainbow palette, while the dataset is loaded asynchronously from an Observable-hosted JSON file.

Fork of D3 v5 Zoomable Sunburst

This interactive sunburst diagram visualizes the hierarchical Flare dataset, showing the relative sizes of its branches and leaves through concentric, angle-based arcs. Clicking an arc zooms in to display that node as the new root, with a smooth 750-millisecond transition animating the arcs and labels via `d3.arc` and `transition.attrTween`. The chart uses D3 v5's `d3.hierarchy`, `d3.partition`, `d3.scaleOrdinal`, and a quantized rainbow color scale, rendering as SVG. Labels rotate and flip to maintain readability, and center-clicking returns to the previous level.

Fork of D3 v5 Zoomable Sunburst

This interactive sunburst diagram visualizes the hierarchical structure of the Flare dataset, with each ring segment representing a category or subcategory whose arc width corresponds to its value. Users can click on any node to zoom into that branch, smoothly animating the re-scaling of arcs and labels via D3 transitions. The visualization is rendered as SVG and uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute layout, while `d3.interpolateRainbow` assigns categorical colors by top-level branch. The code loads data asynchronously through the Observable Standard Library’s `require()` function.

Fork of D3 v5 Zoomable Sunburst

A zoomable sunburst diagram displays the hierarchical structure of the Flare dataset, with each ring representing a level of hierarchy and arc length proportional to size. Clicking a sector zooms into that subtree, re-centering and re-scaling the visualization with a smooth 750-millisecond animation. Built with D3 v5, the SVG rendering uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute the layout, while `transition.attrTween` animates the path geometry and label transforms. The color scale assigns distinct hues to top-level categories based on the data's children.

Fork of Fork of Fork of Fork of D3 v5 Zoomable Sunburst

This zoomable sunburst diagram visualizes the hierarchical structure of the Flare data set, using nested arcs to represent each node's size and depth. Users click an arc to re-center the visualization on that subtree, with a smooth animation transitioning the layout. Built with D3 v5, the code uses `d3.partition`, `d3.arc`, and custom transition logic via `transition.attrTween` to smoothly interpolate arc geometry and label positions. The visualization renders as SVG with interactivity driven by click events on the arcs and a central circle.
