SVG Fundamentals
This example demonstrates the fundamental building blocks of SVG using a static graphic of a single green circle, showing how vector shapes are defined and rendered in the browser. It uses the core SVG `circle` element, with its `cx`, `cy`, and `r` attributes positioning the shape and setting its radius, while the `fill` property applies color. The code is embedded directly in an HTML page, with no JavaScript libraries involved, relying on native SVG syntax to produce the visual output.
