This zoomable sunburst visualization displays hierarchical data from a JSON file using a radial partition layout. Clicking any arc smoothly zooms into that subtree, while clicking the center circle returns to the root. The visualization uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` APIs, with color mapping via `d3.scaleOrdinal` and animation through `transition.attrTween`. SVG rendering with interactive transitions highlights the relationships between nested data categories.

D3 v5 Zoomable Sunburst

This interactive zoomable sunburst displays hierarchical data from a JSON file, showing nested categories and values. The visualization updates its arcs and labels with smooth, 750-millisecond transitions, allowing users to click any arc to zoom in and focus on a sub-branch. Built with D3 v5, it uses the `d3.partition` layout, `d3.arc` for geometry, and `d3.scaleOrdinal` with `d3.interpolateRainbow` for color coding. The code employs `transition.attrTween` for animated path and label updates, with SVG rendering and hover tooltips showing the full path and value.

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 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 visualization displays hierarchical data from the Observable flare dataset through a radial partition layout. The visualization uses D3 v5’s `d3.arc`, `d3.partition`, and `d3.hierarchy` APIs to render SVG paths and labels. Clicking on a partition smoothly zooms into that node using `transition.attrTween` with interpolated arc angles, while a central circle resets the view. Colors are assigned via `d3.scaleOrdinal` with an interpolated rainbow palette, and labels rotate to remain readable throughout the animation.

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 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

This zoomable sunburst chart visualizes hierarchical data from the flare dataset. Clicking a node zooms into that subtree, while a central circle returns to the parent level. The chart uses D3 v5’s `d3.partition` layout and `d3.hierarchy`, rendering arcs as SVG paths with `d3.arc`. Interactive transitions animate via `transition.attrTween`, updating arc geometry and label rotations with color scales from `d3.interpolateRainbow`.
