This example shows a static smiley face drawn as a yellow circle with two black eyes, rendered in SVG. The visualization demonstrates how to integrate D3-style SVG drawing with React by using reusable JavaScript variables for dimensions and offsets. It uses React and ReactDOM to render the SVG elements, with hardcoded values for the face radius, eye position, and stroke width. The code defines constants for width, height, and eye geometry rather than using external data or interactive features, focusing on a minimal component-based approach.
