This example shows a large yellow smiley face rendered with SVG, centered on the screen and resized to fit the browser window. The face includes two black eyes and a curved mouth, drawn using Cartesian coordinates and a polar arc path. React manages the component structure, while D3’s `arc` generator computes the mouth’s path based on inner and outer radii and start/end angles. All shapes are positioned relative to a central translation, with stroke widths and radii defined as constants.
