This example demonstrates how SVG shapes inherit styling from CSS and group elements, using circles, rectangles, lines, and paths. It shows color applied directly via attributes like `fill="red"` or through CSS classes, with stroke properties controlling line appearance. The graphic uses a scale transform to enlarge a 960×500 SVG canvas, while a nested group applies translation and the `.lines` class sets stroke width and color. Rendering relies on raw SVG elements and external stylesheet rules, with no JavaScript libraries involved.
