This example is a minimal HTML page that demonstrates the basic structure of an SVG-based visualization. It renders a single circle element with a radius of 200 units, which is defined directly within an inline `<svg>` tag in the body of the document. The code uses no external libraries or APIs, relying solely on native HTML and SVG markup. The page serves as a bare-bones template, showing how to embed vector graphics in a web page without any scripting or additional dependencies.
