This example shows a simple smiley face built as a static SVG composition, with a yellow circular head, two elliptical eyes, and no mouth or other features. The rendering is driven by React and D3, using hardcoded position and size values for each shape. The code defines the face geometry through SVG `<circle>` and `<ellipse>` elements, while D3’s `arc` function is imported but not actually applied in the visible logic. The example demonstrates basic SVG shape creation within a React component, with an inline CSS style that hides page margins and disables overflow.
