This example demonstrates basic SVG shape rendering within a single HTML file, showing overlapping circles, a line, and two path elements on a 960-by-500 canvas. The code uses the SVG API directly, employing `<circle>`, `<line>`, and `<path>` tags with explicit coordinate attributes and styling properties such as `fill`, `stroke`, and `stroke-width`. It also includes a commented-out `<rect>` element and a YouTube embed link. The overlapping red and green circles illustrate layering in SVG, while the paths show both filled and stroked curve and polyline rendering, with hidden overflow via CSS.
