SVG Fundamentals
This example demonstrates the foundational structure of an SVG graphic embedded directly within an HTML page. It renders a single black circle on a white background, with its position and radius explicitly defined by the `cx`, `cy`, and `r` attributes inside the `<circle>` element. The visualization uses raw SVG markup without any JavaScript or CSS styling, serving as a minimal template for vector graphics. The code relies on the native SVG API integrated into the browser’s DOM, making it a starting point for more complex interactive charts.
