This example demonstrates basic SVG shapes—circles, rectangles, lines, and paths—styled through inline attributes and CSS classes. The code shows how fill colors, stroke widths, transparency, and geometric transforms like scaling and translation affect rendering. It uses raw SVG elements with CSS selectors (`.lines`, `.lines path`) to apply stroke properties, while a `<g>` element groups shapes to share fill and stroke settings. The rendering is pure SVG in an HTML page with no external libraries.
