Test Project
This example displays a simple yellow face composed of a circular background, two eyes, and a curved mouth, all rendered as SVG elements within a React application. The face is drawn using basic circle and path primitives, with the mouth shape generated by the d3-shape `arc` API. D3 v7 is loaded alongside React, and the component structure demonstrates how React components can encapsulate reusable visual parts like `BackgroundCircle`, `Eyes`, and `Mouth`. The code uses fixed numeric constants for sizing and positioning, and renders the face centered within an SVG canvas.
