A simple yellow circle with a black outline, rendered at the center of a 960 by 500 SVG canvas, demonstrates the basic use of SVG elements in a minimal HTML page. The circle is defined directly in the markup with explicit x, y, and radius attributes, while the page relies on CSS to reset margins and hide overflow. This example uses vanilla SVG, not React or a visualization library, and illustrates a static, hand-authored graphic rather than data-driven rendering.
