Hello HTML
This example shows a single yellow circle with a thick black outline centered on an empty SVG canvas. The circle is drawn using an inline SVG element with a radius of 240 pixels, positioned at coordinates (480, 250) within a 960 by 500 viewport. Styling is applied directly through SVG presentation attributes, including fill, stroke, and stroke-width. The page uses plain HTML markup with embedded CSS to reset body margins and hide overflow, while the SVG itself requires no JavaScript libraries or external dependencies.
