This example shows a zoomable sunburst visualization of hierarchical data from the Observable Flare dataset. Users click on arcs to zoom into deeper levels, and a central circle returns to the root. Built with D3 v5, it uses `d3.partition`, `d3.hierarchy`, and `d3.arc` for layout, with `d3.scaleOrdinal` and `d3.interpolateRainbow` for coloring. Transitions animate arc paths and labels via `transition.attrTween` and `d3.interpolate`. The SVG renders with clickable paths and a reset circle.

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

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 example demonstrates a zoomable sunburst visualization of the Flare dataset using D3 v5. It uses `d3.hierarchy` and `d3.partition` to compute the layout, with `d3.arc` for path generation. Interactive zoom transitions are implemented through click handlers and `transition.attrTween` to animate arcs and labels. The visualization renders as SVG with color scales from `d3.scaleOrdinal` and `d3.interpolateRainbow`. The data is loaded asynchronously via an Observable notebook library, with the dataset containing hierarchical filesystem-like size values.

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 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 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.

D3 v5 Zoomable Sunburst

This example shows a zoomable sunburst visualization of the Flare software hierarchy, rendering hierarchical data as concentric arcs with color-coded categories. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and draw the layout in SVG. Clicking an arc animates the view via `transition.attrTween`, interpolating arc angles and radii to zoom into the selected node, while labels fade based on visibility using `d3.interpolate`. Data loads from a remote JSON file.
