Question

I’m building a tree structure (or rather modifying one of the examples with a set of my own data in my own json) and I’m trying to create some functionality:

My tree’s layout is that from the tree example:
http://mbostock.github.com/d3/ex/cluster.html

I am adding (to the circles) an onclick event which I would like to collapse the children of the clicked node. That is to say, when a user clicks the steelblue circle associated with a node, I want that nodes children to disappear.

I’ve scoured the documentation and I haven’t turned up anything which would allow me to make nodes collapse or disappear.

What could I do?

There’s this:

There are a number of other interactive hierarchical layout examples from my SVG Open keynote.
