I'm happy to introduce you with genealogic-d3, a Javascript visualization library to nicely display genealogy trees that I've been working on during the past 3 days.
I'm quite satisfied by the result. You'll find a live demo you can play with at https://chezsoi.org/lucas/genealogic-d3/skywalker.html
I used the Skywalker family as an example, but it is really very easy to adapt to any other family.
On an unrelated note : go watch Predestination, this time-travelling movie is awesome !
