A single gray circle on an empty white field demonstrates the simplest possible SVG rendering of an HTML page. The example shows a static `<circle>` element with a radius of 100 pixels, positioned at coordinates (100, 100) within a 960×500 viewport. The code relies on native HTML and SVG APIs—no external libraries—using inline CSS to remove page margins and hide overflow, while the SVG element itself defines the circle’s shape and placement. This bare minimum setup highlights the foundational structure for any browser-based visualization.
