This example demonstrates the foundational building blocks of SVG graphics by displaying a single red circle at the center of an empty canvas. The visualization shows how basic SVG elements are structured, with the circle's position and size defined by the `cx`, `cy`, and `r` attributes. The rendering relies entirely on native SVG markup embedded directly in the HTML, with no JavaScript libraries or external data sources involved. It serves as a minimal, static illustration of how vector shapes are declared and rendered in a browser.
