D3 tree vertical separation

Question

I am using the D3 tree layout, such as this one: http://mbostock.github.com/d3/talk/20111018/tree.html

I have modified it for my needs and am running into an issue.

Answer 1

As of 2016, I was able to achieve this using just

tree.nodeSize([height, width])

https://github.com/mbostock/d3/wiki/Tree-Layout#nodeSize

The API Reference is a bit poor, but is works pretty straight forward. Be sure to use it after tree.size([height, width]) or else you will be overriding your values again.
