This visualization shows a recursive fractal pattern composed of nested pie chart slices, where each slice is subdivided into smaller slices until reaching a minimum size. The code uses D3 v4 with the d3-component library to create reusable components for slices, connectors, and the recursive fractal group. The pie layout uses d3.pie with custom start and end angles, while d3.arc renders each path. Child radii are calculated based on slice area ratios, and connectors draw stems between parent and child arcs. The generated data follows a fixed ratio hierarchy, rendered as SVG in a single viewport.
