The project was initially created during the 1st Swiss Open Cultural Data Hackathon in 2015.
This simple gadget displays the family tree of a given item from wikidata. It does that by querying Wikidata for the father/mother values. If you want to use it on Wikidata, you can enable it in your user settings (enable "Ancestor").
The tool is available at the following URL: https://tools.wmflabs.org/family/ancestors.php?q=Q7742&lang=en
The gadget takes 3 parameters in the URL:
q(query): this is the root element, it must be a Wikidata ID (e.g. Q7742), default isQ154952(Willem-Alexander of the Netherlands)lang(language): the language in which the data should be displayed, default isenlevel: the amount of levels of the family tree, default is5.
