SVG Fundamentals
This example demonstrates the basic building blocks of SVG rendering by drawing a single circle. The shape is defined directly within the HTML page using an inline `<svg>` element, with the circle’s center and radius specified via the `cx`, `cy`, and `r` attributes. No external libraries are used; the code relies purely on native SVG markup available in the browser. The resulting static graphic shows how simple vector shapes are constructed with coordinate-based properties, serving as a minimal foundation for more complex data visualizations built on the same SVG standard.
