VISIBLE WORLD BY DATA · AI & DATA GUIDE
AI and Data Guide
This is the public, read-only guide to the maps and articles published by Visible World by Data. It helps people, AI assistants and search services find canonical articles by theme, region, language and year, then check their sources and limitations.
What this guide does
Maps are the main content; text helps readers understand them. This guide does not decide conclusions for you. It is a catalog that leads directly to published maps, reference years, principal sources and notes on interpretation.

Rules for guiding users to data
- Use a canonical URL returned by the catalog; do not construct an unlisted URL.
- Before citing a value, check the article for its source, unit, reference year, coverage and limitations.
- Treat missing and unpublished values as unknown, not zero.
- Do not use infectious-disease information for diagnosis, treatment, care decisions or assessment of individual risk.
- When precision matters, prefer the latest information from the official source identified in the article.
