Geni, Graphiz, Dot & Family Tree.

Geni is a genealogy-related social networking website launched in beta mode in January 2007. Since yesterday, the family tree can now be exported as a gedcom-xml file (alpha version).

The following xslt stylesheet transforms the gedcom file into a Graphiz/DOT input which can be used to generate the family tree.
