This example demonstrates how basic SVG shapes—circles, rectangles, lines, and paths—can be styled and transformed using CSS and inline SVG attributes. It shows uncolored shapes in a top group, colored fills in a second group, a translated group with stroke and fill, and a separate group of lines with black strokes and rounded joins. The code uses raw SVG elements within an HTML document, with CSS classes like `.lines` to apply stroke properties. A single SVG `g` transform scales the entire visualization.
