This example demonstrates the foundational structure of SVG graphics by rendering a single circle. It uses plain SVG markup within an HTML page, with the circle’s position and radius set via the `cx`, `cy`, and `r` attributes. The visualization is implemented with raw HTML and SVG, and does not employ any JavaScript libraries or data processing; it relies solely on the browser’s built-in SVG renderer. The result is a simple, static visual illustrating how SVG shapes are defined and displayed.
