A stylized face built from reusable React components uses D3’s `arc()` generator to create the mouth and brow shapes, while SVG circles form the eyes and background. The face, centered via a translated `<g>` group, draws its brow as an arc with controlled angle length and width, and its mouth as a semicircular arc. D3 v7 and React 17 render everything as SVG, with the face’s proportions parameterized through props like `eyeOffsetX`, `mouthRadius`, and `browY`.
