This example shows a yellow smiley face drawn with SVG shapes: a filled circle for the head, two smaller circles for the eyes, and an arc for the mouth. The code uses React to define the SVG elements and the D3 library’s `arc` function to generate the mouth path. The head and facial features are centered using a D3 `translate` transformation, with static numeric values controlling the face’s dimensions and placement. The rendering approach relies on D3 v5 and React 16.9, producing a purely vector-based graphic.
