SVG FUNDAMENTALS
This example presents the fundamental building blocks of SVG graphics within a React application. It renders a single circle element using SVG’s native `cx`, `cy`, and `r` attributes to define the circle’s center coordinates and radius directly in the markup. The code relies on raw SVG markup inside an HTML page, with no external charting libraries or data transformations. It demonstrates the simplest possible static SVG rendering, serving as a minimal baseline for learning how shapes are declared and displayed in a browser.
