This sunburst plot visualizes the hierarchical structure of the Flare dataset, showing nested categories and their relative sizes through concentric arcs. The visualization uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and render the layout in SVG. Clicking an arc zooms inward to focus on that subtree, with `transition.attrTween` and `d3.interpolate` animating the arcs’ angles and radii. Colors are assigned via `d3.scaleOrdinal` with a rainbow interpolation based on top-level category names.

SUNBURST PLOT

This zoomable sunburst plot visualizes the hierarchical flare dataset, displaying nested categories as concentric arcs whose angular width and radial distance encode each node’s relative value. Clicking an inner arc zooms into that subtree, animating the layout and updating visible labels. The visualization uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and draw the geometry, with `transition.attrTween` handling the smooth zoom animation. An ordinal color scale applies a rainbow palette to top-level branches, and SVG paths render the final graphic, which supports interactive navigation through the hierarchy.

Sunburst

A zoomable sunburst chart visualizes the hierarchical flare dataset, showing nested categories as concentric rings where each arc's angular width represents its value. The visualization collapses or expands levels when a user clicks on an arc or the central circle, with smooth transitions animating the radial layout. Built with D3 v5, the code uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute the layout, while `transition.attrTween` and `d3.interpolate` animate arc geometry during zoom. The color scale uses `d3.scaleOrdinal` and `d3.interpolateRainbow`, and data loads asynchronously via the Observable `require` API.

D3 v5 Zoomable Sunburst

This interactive sunburst diagram visualizes the hierarchical structure of the Flare data set, showing the relative size of each category and subcategory through the angle and radius of its arc segments. Users can click on any segment to zoom in and explore deeper levels of the hierarchy, with smooth animated transitions between views. The visualization is built with D3 v5, using the `d3.partition` layout algorithm and `d3.arc` for generating the arc paths, while `d3.interpolate` and `transition.attrTween` handle the animated zooming. The color scheme is generated from a rainbow interpolation across the root categories.

Sunburst Partition

A sunburst diagram displays the hierarchical structure of the Flare dataset, with the root at the center and leaves on the circumference. The visualization uses a radial layout where the angle of each arc encodes the value of the corresponding node. The code employs `d3.layout.partition` and `d3.svg.arc` to compute and draw the arcs, with color assigned by the `category20c` scale. A radio button toggles between sizing arcs by node size or by leaf count, triggering a smooth animated transition via `attrTween` and `d3.interpolate`.

D3 v5 Zoomable Sunburst

This interactive sunburst diagram visualizes the hierarchical structure of the Flare dataset, allowing users to click on any segment to zoom in and explore nested categories. Built with D3 v5, the visualization uses an arc partition layout with a radial layout, where the inner ring represents the root and outer rings show deeper levels. The code leverages `d3.partition`, `d3.hierarchy`, and `d3.arc` for geometry, and employs `d3.interpolateRainbow` for color coding. Animations are handled via `d3.transition` and `transition.attrTween`, smoothly interpolating arc positions and labels during zoom transitions.

D3 v5 Zoomable Sunburst

This zoomable sunburst visualizes the hierarchical structure of the Flare dataset, showing nested categories as concentric arcs. Clicking an arc zooms into that subtree, smoothly animating the radial layout over two seconds. Built with D3 v5, it uses `d3.partition`, `d3.hierarchy`, and `d3.arc` to compute geometry, while `d3.interpolate` and `transition.attrTween` animate the paths and labels. Color assignment uses `d3.scaleOrdinal` with `d3.interpolateRainbow`. The visualization renders as SVG, with tooltips displaying the full path and formatted values.

D3 v5 Zoomable Sunburst

This interactive sunburst visualization displays the hierarchical structure of the Flare dataset, with arc size proportional to leaf-node values and color encoding by top-level category. Clicking any arc zooms to that subtree via animated transitions using `d3.transition` and `transition.attrTween`, while an inner circle returns to the root. Built with D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc`, labels rotate to remain readable. Data loads through the Observable standard library’s `require()` method, and rendering uses SVG with `fill-opacity` to indicate parent-child relationships.
