SVG Fundamentals
This example demonstrates the foundational elements of SVG (Scalable Vector Graphics) using a circle positioned within an inline `<svg>` element. The circle is defined with `cx`, `cy`, and `r` attributes to set its center coordinates and radius, while CSS styles applied in the page's `<style>` block format a separate message. The code relies purely on native HTML, CSS, and JavaScript without any external libraries, showing how SVG shapes can be embedded directly into an HTML document.
