An Interactive Map of the World’s Languages

Sammanfattning

This project thesis presents the development of an interactive language map thatvisualizes the global distribution of spoken languages. The system integrateslinguistic data from Wikidata and geospatial data from OpenStreetMap to allowusers to search for languages and view where they are spoken. The application wasbuilt with a React and TypeScript frontend, a NestJS backend, and a MongoDBdatabase hosted in the MongoDB Atlas cloud. SPARQL queries were used to extractstructured language data, which was cleaned and stored to enable fast queries.The resulting product enables interactive visualization of language regions withsupport for filtering by country or region, viewing speaker statistics, and languagefamily information. The map also supports interactive exploration by clicking on acountry to display information about the languages spoken in that country. Theproject demonstrates how open data sources can be used to create educationalvisualizations, although the quality and coverge of the external databases constrainthe final accuracy.
