This zoomable sunburst visualizes the hierarchical structure of the Flare software class library, showing relative sizes of modules and submodules through nested arcs. Clicking a segment zooms into that branch, while the center circle returns to the root. Built with D3 v5, it uses `d3.hierarchy` and `d3.partition` to compute the layout, `d3.arc` for path geometry, and `d3.interpolateRainbow` for coloring. Animated transitions rely on `transition.attrTween` and `transition.tween` to smoothly update paths and labels during zoom.

D3 v5 Zoomable Sunburst

This D3 v5 zoomable sunburst visualizes the hierarchical structure of the Flare codebase, showing class relationships and their relative sizes. Users click arcs to zoom in and out, with an animated transition of 750ms duration. The visualization uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute the layout, with color encoding applied via `d3.scaleOrdinal` and `d3.interpolateRainbow`. Rendering is done through SVG paths and text elements, with transitions managed by `transition.attrTween` and `d3.interpolate` for smooth angular and radial adjustments.

D3 v5 Zoomable Sunburst

This zoomable sunburst visualizes the hierarchical structure of the Flare dataset, using colored arcs to represent categories and nested segments for subcategories. Clicking a segment smoothly zooms into that branch, animating the radial layout via `d3.transition` and `attrTween`. Rendered with SVG, it leverages `d3.partition`, `d3.hierarchy`, and `d3.arc` to compute the layout, while `d3.scaleOrdinal` and `d3.interpolateRainbow` drive the color scheme, with labels and tooltips (`<title>`) providing details on demand.

D3 v5 Zoomable Sunburst

This zoomable sunburst visualizes the hierarchical Flare dataset, showing relative sizes of its categories through nested arcs. Clicking a node smoothly zooms into its subtree, while a center circle returns to the root. The example uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute layout and shapes, with `transition.attrTween` and `d3.interpolate` animating arc positions. Labels rotate and fade based on visibility, and the color scale applies `d3.interpolateRainbow` per top-level branch, rendered as an SVG with user interaction.

D3 v5 Zoomable Sunburst 1216

This zoomable sunburst visualization displays the hierarchical structure of the Flare data, showing nested categories as concentric arcs whose angular width and radius encode the relative sizes of branches and leaf nodes. Clicking a segment zooms into that subtree, smoothly animating the layout as the clicked node becomes the new root. The D3 v5 code uses `d3.partition` and `d3.hierarchy` for layout, `d3.arc` for path geometry, and `d3.transition` with `attrTween` to interpolate arc positions and angles during zoom animations. A sequential rainbow color scale assigns hues to top-level branches.

D3 v5 Zoomable Sunburst

A zoomable sunburst diagram visualizes the hierarchical flare dataset as concentric arcs, where clicking a segment zooms in to reveal its children. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` for layout, with `d3.interpolateRainbow` for color. Animated transitions via `transition.attrTween` and a `tween` function update arc geometry and label rotations. The SVG rendering includes hover tooltips showing ancestor paths and values, with a central circle to return to the root.

D3 v5 Zoomable Sunburst

This interactive sunburst diagram visualizes the hierarchical structure of the Flare dataset, allowing users to click on any segment to zoom in and explore nested categories. Built with D3 v5, the visualization uses an arc partition layout with a radial layout, where the inner ring represents the root and outer rings show deeper levels. The code leverages `d3.partition`, `d3.hierarchy`, and `d3.arc` for geometry, and employs `d3.interpolateRainbow` for color coding. Animations are handled via `d3.transition` and `transition.attrTween`, smoothly interpolating arc positions and labels during zoom transitions.

D3 v5 Zoomable Sunburst

This zoomable sunburst visualizes the hierarchical structure of the Flare dataset, displaying nested arcs whose size and color encode node values and category. Users click any arc to zoom into that subtree, with smooth 750-millisecond transitions animating arc paths and labels via `d3.transition` and `transition.attrTween`. The code uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and render the SVG layout, while a rainbow color scale distinguishes top-level branches. Data loads asynchronously from the Observable Flare module using `observablehq/stdlib`.

D3 v5 Zoomable Sunburst

This interactive zoomable sunburst visualizes the hierarchical structure of the Flare dataset, where each ring segment represents a node and its size corresponds to a value. Users can click on any segment to zoom in, revealing its children and re-centering the view, or click the central circle to zoom back out. Built with D3 v5, the visualization uses SVG for rendering and employs animated transitions via `transition.attrTween` to smoothly interpolate arc paths and labels as the view changes. The hierarchical data is processed using `d3.hierarchy`, `d3.partition`, and `d3.arc`, with colors assigned via a quantized rainbow interpolator.
