This example displays a simple yellow circle with two black dots, forming a basic smiley face against a white background. It demonstrates the minimal structure required for an SVG visualization embedded directly in an HTML page. The code uses raw SVG elements—`<svg>`, `<circle>`, and inline styling—within a plain HTML document, with no external libraries or data sources. The rendering approach is static SVG, with the page’s body margin and overflow set to hidden via CSS for a clean, full-viewport presentation.
