Hello HTML
This example shows a yellow circle with a black outline centered in an SVG canvas, positioned as the first step toward building a smiley face. It renders two additional circles as potential eyes, offset horizontally from the center, using React 17 and ReactDOM to create the SVG elements. The code references `centerX`, `centerY`, `eyeOffsetX`, and `strokeWidth` variables to control circle positions and stroke styling, though the eye offset on the y-axis (`eyeOffsetY`) is undefined. The visualization uses static, hardcoded dimensions (960×500) and does not include dynamic data.
