D3 v5 Zoomable Sunburst
This interactive visualization presents a hierarchical sunburst chart that displays the file structure of the Flare data. Users click on any arc to zoom in, re-centering the view on that node while smoothly animating the layout to reveal its children. Built with D3 v5, the chart uses the `d3.partition()` layout and `d3.arc()` for rendering, alongside `d3.hierarchy()` and `d3.interpolate()` for smooth transitions between zoom levels. The visualization fetches its data from the @observablehq/flare library and renders via SVG paths and text elements.
