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`.
