This example demonstrates how to combine SVG primitives with CSS styling to create a variety of shapes, including circles, rectangles, lines, and paths, within a fixed 960x500 viewport. The SVG elements are grouped and transformed using attributes like `scale` and `translate` to position and organize the shapes. CSS classes, such as `.lines`, apply stroke properties to the line and path elements. The code uses plain SVG markup and a small D3.js `select` import to set a dynamic message, while the rendering is handled entirely through the SVG DOM.
