This zoomable sunburst chart visualizes the hierarchical flare dataset, where each ring segment represents a category and its size reflects the summed value of its children. Clicking an arc smoothly zooms into that node, re-scaling the partition layout and labels. Built with D3 v5, it uses `d3.partition`, `d3.hierarchy`, `d3.arc`, and `d3.interpolate` within a `transition.attrTween` animation, rendering as SVG with zoom transitions triggered by click events. The flare data is loaded via the Observable standard library’s `require` method.

Fork of D3 v5 Zoomable Sunburst

A zoomable sunburst chart displays the hierarchical structure of the Flare dataset as a radial layout, with each ring segment representing a category and its subcategories. The visualization animates transitions when a user clicks a segment, zooming into that node and its descendants while keeping the surrounding context visible. Built with D3 v5, the chart uses `d3.hierarchy`, `d3.partition`, and a custom `d3.arc` generator to compute the geometry, while `transition.attrTween` smoothly interpolates the arc paths and label transforms during the 750ms zoom animation. The dataset is loaded from an Observable library and rendered as an SVG.

Fork of D3 v5 Zoomable Sunburst

This zoomable sunburst visualization displays the hierarchical structure of the Flare dataset, with each ring segment representing a category or subcategory sized by value. Clicking any arc zooms into that node, smoothly animating the layout so the selected subtree expands to fill the view. The chart is built with D3 v5 using the `d3.partition` layout and custom `d3.arc` paths, rendered as SVG with transitions driven by `transition.attrTween` and `d3.interpolate`. Labels rotate and fade based on visibility thresholds, while a central circle resets the view to the root.

Fork of D3 v5 Zoomable Sunburst

This zoomable sunburst chart visualizes the hierarchical structure of the Flare data, with each ring representing a level and the arc angles proportional to leaf values. The visualization uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.scaleOrdinal` for layout and coloring, plus `transition.attrTween` for animated zooming and panning. The clickable arcs and labels update via interpolated transitions on the SVG paths and text elements, showing node names and values from the flare dataset on hover.

Fork of D3 v5 Zoomable Sunburst

A zoomable sunburst chart visualizes the hierarchical structure of the Flare dataset, with arcs color-coded by top-level category and sized by value. Clicking a segment rotates and scales the visualization to focus on that subtree, using D3 v5 transitions and `transition.attrTween` to animate arc geometry and label positions. The chart renders with SVG, leveraging `d3.hierarchy`, `d3.partition`, and `d3.arc`, while loading data asynchronously via the Observable standard library and `require`.

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 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.

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 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`.
