This example shows a static SVG smiley face rendered directly in an HTML document, with a separate React message displayed as text. The SVG contains three circles—one large yellow face and two black eye outlines—positioned on a 960×500 canvas. It uses React 16 and ReactDOM to render a “Hello React!” div, while the drawing itself relies on native SVG elements (`<svg>`, `<circle>`) rather than any data-driven library. No interactivity or dynamic behavior is present; the visualization is purely declarative and fixed.
