This example demonstrates how to create basic geometric shapes—circles, rectangles, lines, and paths—using SVG elements styled with CSS. It shows how SVG presentation attributes like `fill` and `stroke` can be applied directly to elements or inherited from parent `<g>` groups. The code uses the React framework but primarily relies on raw SVG markup within an HTML file. A CSS class named `.lines` applies stroke properties to line and path elements, with path-specific styling for `stroke-linejoin`. The example illustrates layering, grouping via transforms, and styling inheritance.
