This example demonstrates SVG shapes styled with CSS, illustrating how grouping and transform attributes organize and position circles, rectangles, and paths. The visualization uses inline SVG elements such as `<circle>`, `<rect>`, `<line>`, and `<path>`, with attributes like `fill`, `stroke`, and `stroke-width` controlling appearance. CSS classes in the stylesheet define properties for the line graph, including color and stroke-linejoin. The rendering is purely client-side SVG, with no external JavaScript libraries. The layout applies a scale transform to the entire graphic and a translate transform to center the line elements.
