Academic Genealogy Family Tree with d3?

[pw6...@gmail.com]

Hi,
Would anyone help me with the following question? Thank you so much in advance!
Is it possible to use the powerful d3 to present Academic Genealogy Family Tree in a webpage? e.g. see below, one or two advisors supervised a PhD student. Especially, how to handle the cross generation links (marked in red below)?

Take a look at d3-dagre for that. It's not maintained but it's pretty solid.

https://github.com/cpettitt/dagre-d3

It doesn't handle routing paths around intermediate nodes, so Lichtenburg would be drawn on top of the edge that passes him. That part is kind of tricky and I don't know of js libraries that do that. 

(Pointers welcome if anyone knows of such libraries!)

Cola.js (aka WebCola) will also draw directed graphs but IMO it's much better for undirected graphs.
