A fork of a basic shapes demonstration uses SVG elements styled with CSS to display geometric forms. Circles and rectangles appear in rows, with the first row unfilled, the second row filled with solid red and blue, and the third row given a light cyan fill and black stroke via an inline presentation attribute. A separate SVG path, rendered through the `pathLines` class, draws a black polyline with round line joins and caps across the canvas. The example relies on plain SVG markup and CSS selectors, including the `.pathLines` rule, to define all visual properties.
