This example demonstrates how simple SVG shapes can be combined to create stylized representations of European flags, with a grid of rectangles and lines forming recognizable national symbols. The code uses raw SVG elements like `<rect>`, `<line>`, and `<polygon>` to construct flag patterns, showcasing basic vector graphics principles without any external visualization libraries. The rendering is static, with colors and geometry defined directly in the markup, and includes elements that loosely suggest flags from countries such as France, Germany, and others.
