SVG Fundamentals
This example demonstrates a minimal SVG rendering of a single green circle positioned at coordinates (50, 50) with a radius of 50. The code uses native SVG elements within an HTML document, defined directly in a `<svg>` tag without any JavaScript libraries or data bindings. The static visualization serves as a fundamental starter for understanding SVG markup, highlighting basic shape attributes such as `cx`, `cy`, and `r` for circle positioning and size.
