This example demonstrates how SVG shapes and CSS styling can be combined to render simple geometric elements and paths. The visualization shows a horizontal line and a polyline path with rounded corners and caps, drawn on a 960x500 canvas using embedded SVG markup. The code uses plain SVG elements (`<line>`, `<path>`, and `<g>`) within an HTML structure, with CSS rules in `styles.css` controlling stroke color, width, and line joins. The rendering approach is purely static, showing basic vector graphics without any JavaScript libraries.
