SVG Fundamental
This example demonstrates the bare minimum structure of an SVG graphic embedded in an HTML page. It displays a single circle element with explicit `cx`, `cy`, and `r` attributes, rendered directly by the browser. The code uses raw SVG markup within the HTML body, with no external JavaScript or styling beyond the default presentation. The circle is positioned at coordinates (100, 50) with a radius of 50 units, showcasing the fundamental declarative syntax of SVG shapes. This serves as a foundational template for more complex vector-based visualizations.
