Hello HTML
This example shows a single yellow circle centered on a black-outlined SVG canvas, demonstrating the minimal structure of an HTML page with embedded SVG graphics. The page uses inline CSS to remove margins and hide overflow, while the SVG element is sized at 960 by 500 pixels. The circle is drawn with a fill color, stroke, and stroke-width, all declared as SVG attributes within the markup. No JavaScript libraries or data sources are involved; the visualization relies solely on static HTML and SVG primitives.
