This example demonstrates a minimal SVG rendering setup within an HTML page. The visualization shows a single circle positioned at coordinates (50, 50) with a radius of 50, drawn using the SVG `<circle>` element. The code defines the circle directly inside an `<svg>` tag without any JavaScript or styling. It relies on inline SVG markup for rendering, which is part of the HTML5 specification. The page uses no external libraries or frameworks, serving as a bare-bones demonstration of SVG fundamentals.
