<div dir="ltr">Dear typologists,<div><br></div><div><div>We're proud to announce the release of the WALS Sunburst Explorer (<a href="http://th-mayer.de/wals/">http://th-mayer.de/wals/</a>), an online visualization tool that combines areal and genealogical information of the WALS database (Dryer and Haspelmath 2013; <a href="http://wals.info">http://wals.info</a>).</div><div><br></div><div>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. </div><div><br></div><div>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. </div><div><br></div><div>Thomas Mayer, Bernhard Wälchli, Christian Rohrdantz, Michael Hund</div><div><br></div><div><b>References:</b></div><div><br></div><div>Dryer, Matthew S. and Martin Haspelmath (eds.). 2013.
