The WALS Sunburst Explorer
repost from LingTyp List

Dear typologists,
We're proud to announce the release of the WALS Sunburst Explorer (http://th-mayer.de/wals/), an online visualization tool that combines areal and genealogical information of the WALS database (Dryer and Haspelmath 2013; http://wals.info).
The WALS Sunburst Explorer shows the values for all WALS features by combining the geolocation of the respective languages with their genealogy in a sunburst visualization (Stasko and Zhang 2000). The map and the sunburst are enhanced with interactive functionality and linked views. The user can select a region of the world map to get only those languages spoken in that area displayed in the sunburst. The sunburst itself is zoomable. If you click on a segment, only the languages of the respective subfamily are displayed. The main aim of the WALS Sunburst Explorer is to help its users to distinguish between cases of language contact and genealogical inheritance (Mayer et al. 2014; Rohrdantz et al. 2012). The combination of both types of information can be approached from two different angles. The first approach focuses on a given geographical distribution to explore whether the languages in that area all belong to the same family and thus lead to a clustering of the inherited feature at a certain region of the world or whether there is a real contact situation with unrelated or distantly related languages sharing the feature through borrowing. The second approach concentrates on a given language family to check whether the feature values are the same or similar for all members of the family or whether a divergent feature value can be attributed to the fact that the language is spoken in a different region and might have borrowed the divergent feature from a neighboring language. The WALS Explorer provides the necessary functionalities to tackle both approaches.
