This interactive sunburst chart displays the hierarchical structure of the Flare software system, using segment size to encode file sizes and color to distinguish top-level categories. Built with D3 v5, it renders as SVG and responds to user clicks on segments to zoom in and out of the hierarchy. The visualization uses D3’s `d3.arc`, `d3.partition`, and `d3.hierarchy` APIs to compute the layout, with animated transitions handled through `d3.transition` and `transition.attrTween` for smooth rescaling of arcs and labels. The data originates from the Flare dataset’s JSON representation, sourced from Observable.

Fork of D3 v5 Zoomable Sunburst

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 interactive zoomable sunburst chart visualizes the hierarchical structure of the Flare dataset, representing files and their sizes as concentric arcs. Built with D3 v5, it uses `d3.partition`, `d3.arc`, and `d3.hierarchy` to lay out the radial tree, with animation handled by `transition.attrTween` for smooth zooming on click. The visualization is rendered as SVG, with fill-opacity and label visibility responding to the current zoom level, and colors assigned via `d3.scaleOrdinal` with an interpolated rainbow palette.

Fork of D3 v5 Zoomable Sunburst

This interactive sunburst diagram shows the hierarchical structure of the Flare dataset, with each arc segment representing a category and its size proportional to the data value. Clicking a segment zooms in to reveal that node’s children, while clicking the central circle returns to the previous level, using smooth transitions. The visualization is built with D3 v5, leveraging `d3.partition`, `d3.arc`, and `transition.attrTween` for animation. Data is loaded asynchronously via the Observable stdlib’s `require` and rendered as SVG with color encoding from `d3.scaleOrdinal` and `d3.interpolateRainbow`.

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

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 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 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 Fork of D3 v5 Zoomable Sunburst

This visualization presents a zoomable sunburst of the Flare dataset, showing a hierarchical file structure as multi-level arcs. Rendered with SVG and animated transitions, users click any segment to make it the new root, smoothly redrawing the tree with D3 v5’s updated partition layout. The code uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute geometry, while `transition.attrTween` and `d3.interpolate` animate the arcs and labels. Colors derive from `d3.scaleOrdinal` with an interpolated rainbow range, and the data loads asynchronously from the Observable Flare library.
