Are there any good hierarchial controls for web sites?

I want to generate an hierarchical data representation, more like a family tree rather than the typical tree view.

Something like this

Are ther开发者_开发知识库e any solutions out there to accomplish this? Preferably in .NET but I am considering any solution that this available.

I have my hierarchical datasource, hopefully, I can just feed it into the constructor for this control and have it render on my site. A google and stack exchange search yielded nothing substantive.

Graphviz is the standard. There are bindings for programming languages, as well as GUI editors, etc.
