A simple SVG example demonstrates how shapes and colors can be styled using CSS. It shows circles, rectangles, a line, and a path, with fills and strokes applied both directly as SVG attributes and through a linked stylesheet. The code uses core SVG elements such as `circle`, `rect`, `line`, and `path`, along with grouping and transformation via the `g` element’s `transform` attribute. No JavaScript libraries are involved; rendering relies purely on inline SVG markup and CSS rules for visual customization.
