Hello HTML
This example shows a static SVG smiley face composed of three circles: a yellow head with a black outline and two black eyes. The chart does not visualize any dataset or interactive behavior; it exists purely as a minimal demonstration. The code renders the circles directly in an SVG element within an HTML page, using React and ReactDOM production builds loaded from a CDN. The rendering approach relies on declarative SVG circle elements with explicit coordinates and radius values rather than any data-driven computation or charting library.
