This example displays a single static red rectangle as a placeholder for the flags of the 2026 World Cup. The visualization renders entirely as an SVG element, using a hardcoded `<rect>` shape with a fill color of red. No interactive behavior or data-driven logic is present; the page simply contains an inline SVG with a fixed width and height. The code relies on native SVG markup and does not employ any external libraries such as D3 or additional JavaScript APIs.
