This example uses raw SVG elements to render a grid of alternating blue and red rectangles, with white circles layered on top to create a simple geometric composition. It demonstrates basic SVG fundamentals through direct markup in the HTML file, including rect and circle elements with explicit x, y, width, height, and fill attributes. The CSS includes a hover rule that changes rectangle fill to green over a 3000ms transition, though the rule contains a syntax error using "=" instead of ":". No external libraries or JavaScript frameworks are employed.
