Fork of Hello HTML
This example displays a single full-viewport SVG circle centered on a 960×500 canvas. The page uses raw HTML and SVG markup, with a `circle` element sized to a 250-pixel radius and styled via inline attributes. The CSS resets body margins and hides overflow, ensuring the visualization fills the browser window. The code demonstrates basic SVG rendering without any JavaScript libraries, serving as a minimal illustration of how to embed vector graphics directly in an HTML document.
