The project uses the most recent data from these two trusted sources:

• World Development Indicators - The World Bank
• The World Factbook - CIA

---

Besides the iOS app, there are a few Python scripts to execute the following actions:

• Scrap the country descriptions and energy production from the World Factbook.
• Download the most recent indicators from World Databank using their JSON API (Some updates are quarterly and others yearly).
• Generate plist file with all indicators and descriptions to use with Xcode.
• With population growth data, create colored SVG map.
• Generate 8-bit greyscale map with one color per country. This allows us to identify which country was clicked by reading the color of the selected pixel.
