I've searched my entire life for a way to write simple family trees with custom data, fast, with or without a lot of information.

Then I've come up with this: https://github.com/fiatjaf/rel, which is a simple way to create triples, then render dot graphs, or any template actually, with them. The database is actually a bunch of YAML files representing each node in the graph (the relationships are stored in the nodes' files also).
