A zoomable sunburst visualization displays the hierarchical Flare dataset as concentric arcs, with clickable parent nodes that smoothly re-scale the layout for detailed exploration. Built with D3 v5, the code uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to render SVG paths, while `transition.attrTween` animates arc geometry and label rotations over 750ms. Colors are assigned via `d3.scaleOrdinal` with an interpolated rainbow palette, and node tooltips show ancestor paths and formatted values.

Fork of Fork of D3 v5 Zoomable Sunburst

A zoomable sunburst visualization displays the hierarchical Flare dataset, showing the relative sizes of categories and subcategories through concentric ring segments. Clicking a node smoothly animates and re-scales the chart to focus on that branch, with the central circle resetting the view. Built with D3 v5, it uses `d3.partition`, `d3.hierarchy`, and `d3.arc` for layout and rendering, while `transition.attrTween` and `d3.interpolate` drive the animated transitions between zoom states. Color mapping uses `d3.scaleOrdinal` with `d3.interpolateRainbow`.

Fork of D3 v5 Zoomable Sunburst

This zoomable sunburst chart visualizes the hierarchical flare dataset using D3 v5. The visualization partitions data into a radial layout, with arcs representing nodes and their sizes proportional to values. Clicking an arc transitions the view to zoom into that node, re-scaling the partition layout and updating arc paths and labels. The code uses d3.hierarchy, d3.partition, and d3.arc for the layout and rendering, with d3.transition and attrTween animating the zoom. Colors are assigned via d3.scaleOrdinal with an interpolateRainbow range, and SVG text labels rotate and reposition dynamically.

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 zoomable sunburst visualizes the hierarchical structure of the Flare dataset, with each arc segment representing a node and its size proportional to the node’s value. Clicking a parent arc zooms in, animating the layout so descendants fill the view, while a central circle returns to the root. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and render the radial layout, and `transition.attrTween` with `d3.interpolate` to smoothly animate arc positions and labels. The SVG is styled with a rainbow color scale and hover tooltips show ancestor paths.

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 chart visualizes the hierarchical structure of the Flare dataset, with arcs representing nodes sized by value and color-coded by top-level branch. Clicking an arc zooms and centers the view on that node, while a click on the center circle returns to the root. Built with D3 v5, it uses `d3.partition`, `d3.hierarchy`, and `d3.arc` for layout, with animated transitions driven by `transition.attrTween` and `d3.interpolate` to smoothly update arc paths and labels during zoom.

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 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.
