SVG Fundamentals
This example demonstrates the foundational structure of SVG graphics, showing how a simple circle element is defined within an SVG container. It uses plain HTML and the native SVG API, with the circle’s position and radius set via the `cx`, `cy`, and `r` attributes. The code does not use any JavaScript or data binding, relying purely on declarative markup to render the shape. It serves as a minimal starting point for understanding SVG’s coordinate system and element syntax in a web page.
