This interactive sunburst diagram visualizes the hierarchical structure of the Flare data set, showing the relative size of each category and subcategory through the angle and radius of its arc segments. Users can click on any segment to zoom in and explore deeper levels of the hierarchy, with smooth animated transitions between views. The visualization is built with D3 v5, using the `d3.partition` layout algorithm and `d3.arc` for generating the arc paths, while `d3.interpolate` and `transition.attrTween` handle the animated zooming. The color scheme is generated from a rainbow interpolation across the root categories.

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

A zoomable sunburst diagram displays the hierarchical structure of the Flare data set, visually encoding each category's size through the arc's angular width. The visualization is rendered as SVG via D3 v5, with the root hierarchy partition built using `d3.hierarchy`, `d3.partition`, and the `d3.arc` generator. Clicking a node triggers a smooth animation using D3's `.transition().duration(750)` with `.attrTween` to interpolate arc positions, while fill colors for top-level categories are assigned using a quantized rainbow interpolation via `d3.scaleOrdinal`.

D3 v5 Zoomable Sunburst

This interactive sunburst diagram visualizes the hierarchical structure of the Flare dataset, where each ring segment represents a category and its size corresponds to its value. Users click a segment to zoom into that branch, re-centering the visualization and smoothly animating the arcs and labels. Built with D3 v5, the example uses `d3.hierarchy`, `d3.partition`, and a custom `d3.arc` to compute geometry, while `transition.attrTween` animates the changing path data. The color scheme assigns hues to top-level categories using `d3.scaleOrdinal` and `d3.interpolateRainbow`.

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 diagram visualizes the hierarchical structure of the Flare dataset, with nested arcs representing categories and subcategories. Clicking a node smoothly zooms and re-centers the view on that segment, while fading out irrelevant arcs and labels. Built with D3 v5, it uses `d3.partition`, `d3.hierarchy`, and `d3.arc` to compute the layout, and `transition.attrTween` for animated interpolation between states. Data loads via the Observable standard library, with SVG rendering and a rainbow color scale for top-level branches.

D3 v5 Zoomable Sunburst

This interactive sunburst chart visualizes the hierarchical structure of the Flare dataset, showing file sizes as angular arc lengths. Users navigate the hierarchy by clicking on any segment, which re-centers the visualization on that node's subtree. The implementation is built with D3 v5, using the `d3.arc` generator and `d3.partition` layout to compute segment geometry. Colors are assigned via `d3.scaleOrdinal` with a rainbow interpolation. Clicking triggers a smooth 750-millisecond transition, with `attrTween` and `d3.interpolate` animating the arcs and labels, while the view resets when clicking the innermost circle.

D3 v5 Zoomable Sunburst

An interactive zoomable sunburst chart visualizes the hierarchical structure of the Flare data set. The radial layout partitions the root node into concentric rings, with arc segments representing each category and subcategory; the color of each leaf is inherited from its top-level group. Clicking on an arc zooms into that subtree, expanding its children while hiding others. Built with D3 v5, the visualization uses `d3.partition` for layout, `d3.arc` for path generation, and animated transitions via `transition.attrTween` to smoothly update arc shapes and labels.

D3 v5 Zoomable Sunburst

This interactive sunburst diagram shows the hierarchical structure of the Flare dataset, with each ring segment representing a category and its value. Users can click on any segment to zoom in and focus on that branch, while clicking the central circle returns to the parent level. Built with D3 v5, the visualization uses `d3.hierarchy`, `d3.partition`, and animated SVG transitions to smoothly interpolate arc paths and labels via `transition.attrTween`. Data is loaded from the `@observablehq/flare` module, and colors are assigned using `d3.scaleOrdinal` with a quantized rainbow palette.
