Three Degrees, a web application that displays the relationships between people.
Edit the main.db SQLite3 database in the db directory. The database schema is layed out in db/db_schema.txt. Currently the titles are not implemented, but are meant to further define the relations between two people (ex: Person 1 is the son of Person 2, Person 3 is the teacher of Person 4). The database can be edited live while viewing the HTML page. Opening local_main.html in the browser shows an interactive SVG of the connections between the people in the database.
Currently not implemented, but the idea is to have a database that can be queried by a user only based on the people they know. The idea is to be able to friend people and see how they fit into your web of connections.
