A simple SVG scene displays basic geometric shapes—circles, rectangles, a line, and a polyline path—positioned in an HTML document. The code uses raw SVG elements with CSS styling, including a class selector to apply stroke color and width to the line and path. The shapes demonstrate different fill and stroke properties, such as a red circle, a green rectangle, and a group with a blue fill and black stroke. The SVG canvas is scaled with a transform, and CSS hides page margins and overflow.
