This example demonstrates fundamental SVG shapes and styling within a lightweight HTML page. It renders a horizontal navy line, two overlapping green and blue circles, an irregular path built from arcs and quadratic Bézier curves, a polygon, and an embedded image. The page uses raw SVG markup with CSS for text styling and JavaScript is not employed, though the code includes a global SVG namespace declaration. The composition serves as a bare-bones introduction to SVG rendering in a browser.
