This example demonstrates how SVG shapes and colors can be styled using CSS, presenting circles, rectangles, lines, and a path within a single viewport. The code uses inline SVG elements with attributes like `fill`, `stroke`, and `stroke-width`, while a dedicated stylesheet defines class-based rules for the line and path elements, including `stroke-linejoin` and `stroke-linecap`. A nested `<g>` element applies a shared fill and stroke, and transforms such as `scale` and `translate` position the shapes. The rendering approach is purely SVG with CSS styling.
