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.

<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

Fork of Fork of D3 v5 Zoomable Sunburst

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

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 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 zoomable sunburst visualization displays the hierarchical structure of the Flare dataset, with each ring segment representing a category or subcategory sized by value. Clicking any arc zooms into that node, smoothly animating the layout so the selected subtree expands to fill the view. The chart is built with D3 v5 using the `d3.partition` layout and custom `d3.arc` paths, rendered as SVG with transitions driven by `transition.attrTween` and `d3.interpolate`. Labels rotate and fade based on visibility thresholds, while a central circle resets the view to the root.

Fork of D3 v5 Zoomable Sunburst

This zoomable sunburst chart visualizes the hierarchical structure of the Flare data, with each ring representing a level and the arc angles proportional to leaf values. The visualization uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.scaleOrdinal` for layout and coloring, plus `transition.attrTween` for animated zooming and panning. The clickable arcs and labels update via interpolated transitions on the SVG paths and text elements, showing node names and values from the flare dataset on hover.

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 Fork of D3 v5 Zoomable Sunburst

A zoomable sunburst visualization displays the hierarchical Flare dataset, showing the relative sizes of categories and subcategories through concentric ring segments. Clicking a node smoothly animates and re-scales the chart to focus on that branch, with the central circle resetting the view. Built with D3 v5, it uses `d3.partition`, `d3.hierarchy`, and `d3.arc` for layout and rendering, while `transition.attrTween` and `d3.interpolate` drive the animated transitions between zoom states. Color mapping uses `d3.scaleOrdinal` with `d3.interpolateRainbow`.

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.
