This example displays a set of geometric shapes—circles and rectangles—arranged in a grid, with a separate group of lines and a polyline path drawn below. It demonstrates basic SVG styling and grouping using inline attributes, CSS classes, and the `<g>` element. The rendering relies on raw SVG markup within an HTML file, with CSS controlling margins, overflow, and stroke properties for the line group. SVG transform functions handle scaling and translation, while the `fill`, `stroke`, and `stroke-width` attributes define visual appearance.
