This example demonstrates basic SVG shapes and CSS styling in a static visualization. It shows circles and rectangles with varying fill colors, stroke properties, and a line with a polyline path, all grouped and transformed within an SVG canvas. The code uses raw SVG elements like `circle`, `rect`, `line`, and `path`, along with CSS classes to control stroke appearance and line joins. A `<g>` element applies a translation transform, and inline attributes set fill and stroke values directly. The rendering is entirely client-side via SVG, with no external JavaScript libraries or data sources.
