Renders SVG circle segments that appear one by one using stroke-dasharray animation driven by interpolate(), building up a complete pie chart. Each segment gets its own color and label. Use for market share breakdowns, budget allocations, survey results, or any proportional data.
Segment data, colors, and legend labels are configurable. A dark centre circle provides visual balance. The staggered reveal makes each data slice feel intentional — ideal for presentation videos and data storytelling.
