This example demonstrates a collection of basic geometric shapes—circles, rectangles, a line, and a path—rendered within a single SVG canvas. It shows how presentation varies: shapes appear both with default black fills and with explicit `fill` attributes, while a group applies a unified light-blue fill and black stroke. The example uses plain SVG markup alongside CSS to style elements, specifically targeting elements with the `.lines` class to set stroke color and width, and further styling the path within that group. A `transform` scales the entire composition.
