How it works

This tool visualizes the hierarchical relationships between the world's major language families using an interactive tree structure. All data is embedded directly in the page and processed client-side.

• Language families: the top-level nodes represent major families such as Indo-European, Sino-Tibetan, Afro-Asiatic, and others — each grouping languages that descend from a common ancestor.
• Branches and groups: families subdivide into branches (e.g., Germanic, Romance) and further into groups (e.g., West Germanic, North Germanic), reflecting historical divergence.
• Individual languages: leaf nodes show specific languages with approximate native speaker counts and regions where they are spoken.
• Search: type any language or family name to filter and highlight matching nodes instantly. The tree auto-expands to reveal matches.
• Details panel: click any node to view additional information including type classification, speaker estimates, geographic regions, and notes.

All data is stored locally in the page — no network requests are made. Speaker counts are approximate and based on widely cited linguistic references.
