A collection of basic SVG shapes demonstrates how presentation can be controlled through inline attributes and external CSS. Circles, rectangles, and a polyline are drawn with default black fills, then customized with explicit fill colors, stroke widths, and a translated group using a light blue fill. A separate line and path, grouped under a class `lines`, receive black strokes and rounded joints via stylesheet rules. The example uses raw SVG elements within an HTML document, styled by a linked `styles.css` file, with no JavaScript or data binding involved.
