This example shows a static yellow smiley face with two black eyes and a curved mouth, rendered as an SVG graphic. The face is built by drawing a large yellow circle with a black stroke, two smaller circles for the eyes, and an arc for the smile, all positioned within a 960×500 viewport. The code combines React for the user interface component structure and D3 v5 for SVG element creation, using basic circle and path SVG primitives. The project loads React 16.9, ReactDOM, and D3 5.11 via CDN, with the face geometry defined manually in JavaScript rather than derived from data.
