A single static SVG graphic demonstrates primitive shapes and color styling through both inline attributes and CSS rules. The markup places circles, rectangles, lines, and a polyline path within nested `<g>` groups, with fill and stroke set directly on elements for some shapes and inherited via CSS classes for others. The stylesheet applies stroke widths, line joins, and caps to the line and path elements. No data is loaded; the example illustrates basic SVG structure and CSS selectors for visual customization.
