This example demonstrates the absolute minimum required to render vector graphics on a web page, using an inline Scalable Vector Graphics (SVG) `<circle>` element to draw a simple yellow smiley face with two black eyes. It does not employ any JavaScript libraries, instead relying purely on static SVG markup embedded directly within the HTML document. The page's body has zero margin and hidden overflow, ensuring the 960 by 500 pixel SVG canvas fills the viewport without scrollbars. The code serves as a bare-bones starting point for understanding how SVG shapes are defined and styled.
