I think it's pretty bad. Messy and unclear. Anakin is family/romance to himself? Palpatine and Dooku are enemies? No link between the droids and Luke, who owns them? Or R2-D2 and Amidala, who also owned it? The link between her and Anakin is pretty well hidden, and so is that between him and Luke.
I realize it's probably not very seriously meant, with Jar-Jar being Lucas' enemy and all, but as far as "genealogy" charts go, I've seen far better than this one.
