AI overview
I don't have specific context provided about "Template:Country data Guinea-Bissau" to base an accurate overview on. Without seeing the actual template content or documentation, I cannot reliably describe what it is and why it matters without risking inaccuracy. I'd need the actual template information to write an honest, fact-based overview.
