World History & Civilization Atlas

13 eras from Classical Antiquity (500 BC) to the Modern Era (2025). Each era includes a unique color, date range, and contextual description. Era transitions update all globe layers, atmosphere color, and the timeline indicator simultaneously.

60+ empires rendered as globe.gl point clouds with radii proportional to territorial extent. From the Achaemenid Persian Empire to modern superpowers, each includes capital city, peak population, and precise date range. Points use per-empire colors with semi-transparency for overlap visibility.

8+ world religions tracked across all 13 eras with regional percentage data. Each religion–region pair is a separate point, sized by adherent percentage. Colors follow consistent religion-specific palettes (e.g., Christianity=blue, Islam=emerald, Hinduism=amber, Buddhism=violet).

80+ pivotal events categorized by type (war, revolution, treaty, formation, collapse, discovery, partition) and significance (major, significant, notable). Point size scales with significance; color encodes event type. Click any event for year, description, and historical context.

40+ migration flows rendered as animated dashed arcs on the globe. Each arc connects origin and destination coordinates with animated dash movement indicating direction. Includes people count, reason for migration, and era-specific coloring. From the Bantu Expansion to the Syrian Refugee Crisis.

GeoJSON country polygons (110m resolution) provide modern political boundaries as context. Borders appear as subtle white outlines, highlight yellow on hover, and support click-to-fly-to interaction. The same proven pattern used across all GRIP 3D globe use cases.
