This example demonstrates basic geometric shapes rendered with SVG and styled using CSS. It shows circles, rectangles, lines, and a path within a container that applies scaling and translation transformations. Specific elements use inline `fill` attributes for color coding, while a group with class `lines` uses CSS rules to define stroke color, width, and line join rounding. The SVG markup is embedded directly in the HTML, with `transform` attributes controlling layout and positioning. No additional libraries are used beyond the native SVG and CSS APIs.
