This example demonstrates how to render basic geometric shapes within an SVG container on a web page, using a combination of SVG elements and CSS for styling. It shows a group of gray rectangles, circles, lines, and a polygonal path, all positioned with explicit coordinates and transform attributes. The rendering relies on the native SVG API for shapes, while external CSS handles global reset and overflow properties. A minimal JavaScript snippet logs a message to the browser console, though the visualization itself is purely declarative markup.
