This example demonstrates a hand-coded SVG composition of basic geometric shapes—circles, rectangles, lines, and a path—styled with CSS and rendered within an HTML page. It shows how SVG elements respond to presentation attributes like fill, stroke, stroke-width, and grouping via `<g>` tags. The code uses no external libraries, relying on native SVG and a small JavaScript console log. The dark background and vibrant shapes highlight how inline styles and CSS classes interact with SVG rendering.
