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.

<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, 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 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 visualizes the hierarchical structure of the Flare dataset, with each arc segment representing a data category and its size proportional to value. Clicking an arc zooms in to make that node the new root, animating the repositioning of all visible arcs and labels. Built with D3 v5, it uses `d3.partition`, `d3.hierarchy`, and `d3.arc` to compute and draw the layout, while `transition.attrTween` smoothly interpolates arc geometry during zoom. The visualization renders in SVG and applies a rainbow color scale based on top-level categories.

Fork of D3 v5 Zoomable Sunburst

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`.

Fork of D3 v5 Zoomable Sunburst

This zoomable sunburst visualizes the hierarchical Flare dataset, showing the relative sizes of categories and subcategories in a radial layout. Users click on arcs to zoom into deeper levels, with smooth animated transitions between views. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute the layout, while `d3.interpolate` and `transition.attrTween` animate arc paths and label positions. The color scale maps top-level categories using `d3.scaleOrdinal` and `d3.interpolateRainbow`.

Fork of D3 v5 Zoomable Sunburst

This zoomable sunburst diagram visualizes the hierarchical Flare dataset, showing the relative sizes of categories and subcategories through nested arcs. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to render the SVG, with an ordinal color scale based on `d3.interpolateRainbow`. Clicking a node triggers smooth animated transitions via `transition.attrTween` and `d3.interpolate`, rescaling arcs and labels to zoom into the selected branch. Labels rotate and reposition based on arc angles, and tooltips via `title` show full paths and numeric values.

Fork of D3 v5 Zoomable Sunburst

This interactive sunburst diagram visualizes the hierarchical Flare dataset, showing the relative sizes of its branches and leaves through concentric, angle-based arcs. Clicking an arc zooms in to display that node as the new root, with a smooth 750-millisecond transition animating the arcs and labels via `d3.arc` and `transition.attrTween`. The chart uses D3 v5's `d3.hierarchy`, `d3.partition`, `d3.scaleOrdinal`, and a quantized rainbow color scale, rendering as SVG. Labels rotate and flip to maintain readability, and center-clicking returns to the previous level.

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.
