This interactive sunburst diagram shows the hierarchical structure of the Flare dataset, with each arc segment representing a category and its size proportional to the data value. Clicking a segment zooms in to reveal that node’s children, while clicking the central circle returns to the previous level, using smooth transitions. The visualization is built with D3 v5, leveraging `d3.partition`, `d3.arc`, and `transition.attrTween` for animation. Data is loaded asynchronously via the Observable stdlib’s `require` and rendered as SVG with color encoding from `d3.scaleOrdinal` and `d3.interpolateRainbow`.

<br></br> Ported from this Observable notebook for this forum thread. Many thanks to Bryan Gingechen who answered my question about the necessary steps to get from an (Observable) JavaScript notebook to a vanilla JavaScript index.html. He presented his solution on blockbuilder.org

Fork of D3 v5 Zoomable Sunburst

This interactive sunburst diagram visualizes the hierarchical Flare dataset, displaying the relative sizes of categories and subcategories as concentric arcs. Users can click on any arc to zoom into that branch, with smooth animated transitions between views. The visualization uses D3 v5’s `d3.partition` layout and `d3.arc` generator to compute arc geometry, while `transition.attrTween` and `d3.interpolate` animate changes. A categorical color scale assigns hues to top-level nodes, and labels rotate and fade based on arc visibility thresholds. The data is loaded from an Observable-hosted JSON module.

Fork of D3 v5 Zoomable Sunburst

This interactive sunburst chart visualizes the hierarchical structure of the Flare dataset, showing relative sizes of categories and subcategories as concentric arcs. Users click any segment to zoom into that branch, with smooth 750ms transitions animating the radial layout. Built with D3 v5, the visualization uses `d3.partition` for layout, `d3.arc` for path generation, and `d3.interpolateRainbow` for color coding. SVG rendering with `transition.attrTween` smoothly updates arc geometry and label positions during zoom interactions.

Fork of D3 v5 Zoomable Sunburst

This interactive sunburst visualization displays the hierarchical structure of the Flare dataset, where each arc segment represents a node and its angular width encodes the node's value. Clicking a segment zooms in to show that node as the new root, with smooth animated transitions updating arcs and labels. Built with D3 v5, the visualization uses `d3.hierarchy`, `d3.partition`, and `d3.arc` for layout, while `transition.attrTween` animates the changing arc paths during zoom. Color is assigned per top-level category using a rainbow scale.

Fork of D3 v5 Zoomable Sunburst

This interactive sunburst diagram visualizes the hierarchical Flare dataset, showing the relative sizes of categories and subcategories through radial arcs. Users can click on any arc to zoom into that portion of the hierarchy, with smooth animated transitions repositioning the layout. The visualization is built with D3 v5, using `d3.partition` to compute the layout, `d3.arc` for arc paths, and `transition.attrTween` to animate changes between states. Colors are assigned via `d3.scaleOrdinal` with an interpolated rainbow palette, and labels rotate to remain readable at various depths.

Fork of D3 v5 Zoomable Sunburst

This interactive sunburst visualization displays the hierarchical structure of the Flare dataset, with each arc’s size proportional to its value. Clicking a slice zooms in to reveal its children, using D3 v5’s `d3.partition`, `d3.hierarchy`, and `d3.arc` for layout and rendering. Animated transitions via `transition.attrTween` and `d3.interpolate` smoothly update arc positions and labels, while colors are assigned using `d3.scaleOrdinal` and `d3.interpolateRainbow`. The visualization renders as SVG.

Fork of D3 v5 Zoomable Sunburst

This sunburst visualization displays the hierarchical structure of the Flare data set, with each arc representing a node and its size proportional to the node’s value. Clicking an arc zooms in to show that node’s children, while clicking the center circle returns to the previous level. The visualization uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` APIs, with smooth transitions animated via `transition.attrTween`. Color is assigned using `d3.scaleOrdinal` with a rainbow palette, and the SVG is rendered from the `flare.json` data file.

Fork of D3 v5 Zoomable Sunburst

This interactive sunburst chart displays the hierarchical structure of the Flare software system, using segment size to encode file sizes and color to distinguish top-level categories. Built with D3 v5, it renders as SVG and responds to user clicks on segments to zoom in and out of the hierarchy. The visualization uses D3’s `d3.arc`, `d3.partition`, and `d3.hierarchy` APIs to compute the layout, with animated transitions handled through `d3.transition` and `transition.attrTween` for smooth rescaling of arcs and labels. The data originates from the Flare dataset’s JSON representation, sourced from Observable.

Fork of D3 v5 Zoomable Sunburst

This interactive sunburst visualization displays the hierarchical flare dataset, using arc segments sized by value and colored by top-level category. Clicking a segment zooms into that subtree, with smooth animated transitions reshaping all arcs and labels. Built with D3 v5, the example uses `d3.hierarchy`, `d3.partition`, `d3.arc`, and `d3.interpolate` to drive the SVG rendering and 750ms transition animations. The data is loaded via the Observable standard library's `require` function.
