This example demonstrates a minimal SVG rendering of a single circle, serving as an introduction to fundamental SVG elements and attributes. The circle is positioned with `cx`, `cy`, and `r` attributes inside an inline `<svg>` tag on a basic HTML page. The code uses plain JavaScript and CSS without any external libraries, showcasing how raw SVG markup can be embedded directly in HTML. The visualization displays a static shape rather than data-driven content, highlighting the geometric primitives that form the basis for more complex charting and interactive graphics.
