Fork of Hello HTML
This fork of the Hello HTML example displays a single unfilled circle centered in an SVG canvas. The page renders the circle using a basic SVG `<circle>` element with an `r` attribute of 200, set within a 960 by 500 pixel viewport. The code relies on native HTML and SVG APIs, with no external JavaScript libraries or data sources involved. The circle is the only visual element, and the stylesheet contains an empty `body{}` rule, leaving the page otherwise unadorned.
