A React-rendered SVG face shows a yellow circle with black stroke, two dark eye circles, and an arc-based mouth created with d3.arc. The code uses React 17 and D3 v7, with the mouth path generated via arc start and end angles. Eye positions and radii are fixed constants, and the background circle’s radius derives from the viewport height minus stroke width. The visualization demonstrates basic SVG shape composition within a React component, using D3 only for the arc path generator.
