This example displays a static SVG scene with a green circle and a red rectangle outlined in blue, set above a large “Hello HTML!” message. It demonstrates the foundational use of raw HTML, CSS, and JavaScript within a single document. The SVG elements are drawn using the standard `circle` and `rect` tags, while the message’s appearance is controlled through a CSS class rule. The code does not rely on external libraries; instead, it serves as a minimal starter template where the browser’s native rendering of SVG and CSS provides the entire visual output.
