This example displays a gallery of basic geometric shapes drawn on a responsive HTML5 Canvas, including filled and outlined rectangles, circles, triangles, lines, ellipses, rounded rectangles, and a star. The canvas uses the Canvas 2D API with methods like `fillRect()`, `arc()`, and `quadraticCurveTo()` to render each shape. The drawing routine redraws all shapes whenever the window is resized, adapting the layout to the available screen space.
