This example shows a stylized smiley face rendered as a path with a circular arc for the mouth, centered within an SVG canvas. The face is drawn using React components, with the mouth generated by D3’s `arc` API to create an annular sector, while a vertical line serves as a subtle background element. The code leverages React’s ES6 modules and the D3 library, with random parameters for stroke width and mouth radius, and uses a `FaceContainer` to translate the coordinate system to the canvas center.
