This example presents a stylized smiling face built as a React component, using SVG for all rendering. The face consists of a yellow circle with a blue stroke, two red eyes positioned symmetrically, and a mouth drawn with the d3.arc() path generator. The code integrates React 18 with D3 v7, computing circle positions via absolute offsets and generating the mouth arc from defined start and end angles. The visualization is static, with no interaction or data binding beyond the hardcoded layout constants.
