Hi,

There's nothing built-in. I think this kind of layout will work only if your tree has two levels, e.g. it's not clear how the levels should be split if you have some large branches growing from the HI1 and HP nodes. If your trees are of two levels, you could arrange all the root's children in a four-column grid below the root (similar to what's shown in the Predefined Shapes example) and then set the links' ControlPoints to appropriate shapes.

If you need to display arbitrarily deep trees, try using the TreeLayout settings from the DirTree example - they will let you fit very deep trees in a page's width, especially if you set negative LevelDistance (so that nodes from adjacent levels overlap a bit horizontally).

I hope that helps,
Stoyan
