SVG Fundamentals
This example demonstrates the fundamental building blocks of SVG by rendering a single circle shape. The code uses the basic SVG `circle` element with `cx`, `cy`, and `r` attributes to define its center coordinates and radius within an inline `<svg>` container. No external JavaScript libraries are involved; the scaffolding is plain HTML with no styling or interaction. The visualization serves as a minimal, static illustration of how vector graphics are structured, showing only a filled black circle positioned at the top-left of the viewport.
