This example demonstrates how to draw basic geometric shapes with SVG and style them using CSS. It uses raw SVG elements like `circle`, `rect`, `line`, and `path` within a `<g>` container, with CSS classes controlling stroke and fill properties. The code shows shape attributes set inline (e.g., `fill`, `stroke-width`) and via a stylesheet, including a group with translated coordinates and another with a rounded path. No JavaScript or external libraries are involved; the visualization relies entirely on static SVG markup and a linked `styles.css` file.
