This example showcases basic geometric shapes—circles, rectangles, lines, and paths—rendered within an SVG canvas. It demonstrates how CSS classes, such as `.lines`, can control stroke color and width, while SVG presentation attributes like `fill`, `stroke`, and `transform` (including `scale` and `translate`) style individual elements. The code uses raw SVG markup in an HTML file, linked to an external stylesheet, to combine vector graphics with cascading style rules.
