A React and D3 v7 donut chart compares AI consistency (95%) with human variability (5%) in image generation. Each colored arc is rendered using d3.pie and d3.arc generators, with icons and percentage labels positioned via arcGenerator.centroid. Clicking a segment toggles an info panel displaying category details while dimming inactive arcs. Data is hardcoded in App.jsx, and the chart responds to container resize events through a ResizeObserver hook.
