This example demonstrates basic SVG shapes—circles, rectangles, lines, and a path—with CSS-driven styling and color fills. It shows how element attributes like fill and stroke can be overridden by CSS rules, and how grouped elements inherit shared properties. The code uses raw SVG markup within an HTML file, with a linked CSS file controlling stroke width, line joins, and cap styles. Rendering relies entirely on the browser’s native SVG support, with no external libraries.
