This visualization shows a yellow smiley face centered on an SVG canvas, with two black eyes and a curved mouth formed by a thick arc. The face is drawn using React components that render SVG elements, while the mouth is generated with D3’s `arc()` generator, specifying inner and outer radii and angular start and end points. All shapes are positioned relative to a central transform group, using fixed pixel coordinates derived from the 960x500 viewport. The code relies on React 17, ReactDOM, and D3 v5, with no external data source.
