This example shows a simple, stylized face composed of geometric shapes, including a yellow circular background, two black eyes, and a curved mouth. The face is constructed using React components for each part, which are assembled within a React application. The rendering is handled through SVG elements, and the mouth’s curve is generated using the D3.js `arc` function from the d3 library, with its radius and width defined as properties. The code uses React and D3, with the face centered and scaled based on specified dimensions.
