SVG Fundamentals
This example shows a minimal SVG scene with a single circle, demonstrating the basics of drawing shapes in a web page. The circle is positioned with an `cx` attribute of 50, though no `cy` or `r` values are provided. The code relies on plain HTML and SVG markup embedded directly in the document body, with no JavaScript, CSS styling, or external libraries. It serves as a starter template for understanding how SVG elements are structured, using the native `circle` tag within an `<svg>` container.
