This D3 v5 zoomable sunburst visualizes a hierarchical dataset, using colored arcs to represent nested categories from the flare data loaded via the Observable standard library. Clicking an arc animates a zoom into that node, with transitions driven by `d3.arc` interpolation and `transition.attrTween` to smoothly reshape arcs and labels. The SVG rendering uses `d3.partition`, `d3.hierarchy`, and ordinal color scales, with visibility logic filtering arcs and text based on computed angular and radial bounds.

D3 v5 Zoomable Sunburst

This interactive sunburst visualization displays a hierarchical dataset from the Observable “flare” library. The circular treemap partitions data by category and subcategory, with each arc’s size reflecting the value. Clicking an arc smoothly zooms to that node, re-centering the layout and fading out unrelated segments, using `d3.hierarchy`, `d3.partition`, and `d3.arc` for geometry and `transition.attrTween` for animation. The SVG output is styled with `d3.scaleOrdinal` and `d3.interpolateRainbow` for color, while labels and tooltips are generated via D3 selections.

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

The zoomable sunburst visualizes hierarchical data from the Observable Flare dataset as concentric arcs, where clicking a node recenters and rescales the view on that subtree. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` for layout and rendering, with smooth 750ms transitions driven by `transition.attrTween` and interpolation of arc geometry. Color is assigned per top-level branch via a rainbow ordinal scale, and labels rotate radially with visibility filtering.

D3 v5 Zoomable Sunburst

This D3 v5 zoomable sunburst visualizes hierarchical data from the Observable @observablehq/flare dataset. Users click arcs to zoom into a category, triggering animated transitions that recompute arc angles and radii via `d3.partition` and `d3.hierarchy`. The code uses `d3.arc`, `d3.scaleOrdinal`, and `d3.interpolateRainbow` for coloring, with SVG paths and text labels rendering the radial layout. `transition.attrTween` animates the shape and position of arcs and labels over 750 milliseconds, while `d3.format` displays numeric values.

D3 v5 Zoomable Sunburst

An interactive zoomable sunburst visualization displays hierarchical data from the Observable Flare dataset, where clicking on an arc zooms into that subtree. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to render SVG paths with animated transitions via `transition.attrTween`. Color is assigned by a `d3.scaleOrdinal` interpolating rainbow hues across top-level children, while labels rotate and fade based on arc visibility. Clicking the center circle returns to the root level.

D3 v5 Zoomable Sunburst

This zoomable sunburst visualizes hierarchical data from an Observable flare dataset, letting users click arcs to zoom into nested categories. Built with D3 v5, it renders the chart as an SVG using `d3.partition` and `d3.arc`, with animated transitions via `transition.attrTween` that smoothly interpolate arc positions. Colors derive from a rainbow scale based on top-level children, while labels dynamically appear or fade based on arc visibility. The example also includes a central reset circle to navigate back to the root.

D3 v5 Zoomable Sunburst

This interactive sunburst visualization displays the hierarchical structure of the Flare dataset, with arc size proportional to leaf-node values and color encoding by top-level category. Clicking any arc zooms to that subtree via animated transitions using `d3.transition` and `transition.attrTween`, while an inner circle returns to the root. Built with D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc`, labels rotate to remain readable. Data loads through the Observable standard library’s `require()` method, and rendering uses SVG with `fill-opacity` to indicate parent-child relationships.

D3 v5 Zoomable Sunburst

This zoomable sunburst chart displays hierarchical data as concentric arcs, where clicking a segment zooms in to show its children while the central circle returns to the root. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to render the SVG layout, with `transition.attrTween` animating arc positions and label transforms. The visualization loads the flare dataset via Observable’s stdlib and applies a rainbow color scale based on top-level categories.
