This example demonstrates basic SVG shapes—circles, rectangles, lines, and a path—grouped and transformed within a fixed 960×500 viewport. It shows how presentation attributes like `fill`, `stroke`, and `stroke-width`, along with CSS rules targeting the `.lines` class, style the geometry. The code uses native SVG elements and the `transform` attribute for scaling, translation, and grouping, with no external JavaScript libraries. Static data is hardcoded directly in the markup, and rendering relies entirely on the browser’s SVG support.
