This example displays three basic SVG shapes—a red circle, a yellow rectangle with a navy border, and a navy line—all positioned directly within an SVG element on a minimal HTML page. The rendering relies on the browser’s built-in SVG support, with shapes defined declaratively via attributes like `cx`, `r`, `x`, and `y`. The page uses no external libraries, showcasing raw HTML and SVG markup for static vector graphics. It serves as a starter template for embedding shapes without JavaScript or data.
