This example demonstrates basic SVG shapes—circles, rectangles, lines, and paths—styled with CSS classes and inline attributes. It shows how to compose geometric primitives within nested groups, applying transforms like `scale()` and `translate()`, and using both CSS rules and presentation attributes for fill, stroke, and stroke-width. The visualization uses HTML5 `<svg>` elements directly in the markup, with JavaScript and CSS linked externally, and does not include any data or interactive behavior.
