This example demonstrates the essential building blocks of SVG graphics by rendering a single circle element within an HTML document. The visualization showcases the core syntax of the SVG markup language, using attributes such as `cx`, `cy`, and `r` to define the circle’s center coordinates and radius on a two-dimensional plane. The code relies on native SVG support built directly into modern web browsers, requiring no external JavaScript libraries or frameworks. The circle is drawn with a default black fill, which can be customized through standard SVG presentation attributes for stroke and fill styling.
