We present GlottoVis, a system designed to visualize language endangerment as collected by UNESCO and descriptive status as collected by the Glottolog project. Glottolog records bibliographic data for the world’s (lesser known) languages. Languages are documented with increasing detail, but the number of native speakers of minority languages dwindles as their population shifts to other more dominant languages. Hence one needs to visualize documentation level and endangerment status at the same time, to browse for the most urgent cases (little documentation and high endangerment) and to direct funding aimed at describing endangered languages. GlottoVis visualizes these two properties of languages and provides an interface to search and filter. Our tool is web-based and is comprised of glyphs on a zoomable geographic map. Clustering and (visual) data aggregation are performed at each zoom level to avoid overlap of glyphs. This reduces clutter and improves readability of the visualization. Preliminary tests with expert users confirm that our tool supports their desired workflow well.
