This example shows a simple smiling face rendered as an orange SVG circle with a green stroke and two smaller circles for eyes, using React to define the component structure. The code leverages React’s JSX syntax and creates SVG elements with computed positions based on width, height, and offsets. It uses D3 version 7 from a CDN, though no D3 functions are explicitly called, and relies on ReactDOM to render the component into the page root. The visualization demonstrates basic SVG drawing within a React framework, with a fixed 800x400 canvas.
