This example demonstrates how SVG shapes can be styled using both presentation attributes and CSS. It draws circles, rectangles, lines, and paths on a 960×500 canvas, with a transformation that scales the content. The code uses inline `fill` and `stroke` attributes, a grouped element with inheritance of stroke and fill properties, and CSS classes (`.lines`, `.lines path`) to control stroke color, width, and line joins. The SVG is embedded directly in HTML and styled with an external stylesheet.
