Hello HTML
This example shows a single large yellow circle rendered inside an SVG element, representing a minimal HTML page. The circle is centered on a 960 by 500 canvas with a thick black stroke, and two smaller unfilled circles sit inside it as decorative elements. The page uses an inline SVG with standard SVG circle elements, styled via CSS attributes like `fill` and `stroke-width`. It demonstrates a bare-bones HTML document structure, with no external libraries or JavaScript.
