why is the flare.json file used in the non-zooming version http://bl.ocks.org/mbostock/4347473 not interchangeable with the zoomable icicle readme.json file?

The flare.json has children text while the readme.json does not, changing readme.json to flare.json in the zoomable version causes the isicle view not to load at all.

How to make the zoomable version version work with the flare.json file? Ideally how to make it so the nonzoom version becomes zoomable using flare.json (children).

Using the wiki on https://github.com/mbostock/d3/wiki/Partition-Layout#nodes and not having any luck with using partition.nodes or partition.children...(i'm new to d3 (day2-self taught) so this is probably super easy fix for pros)...any helpful tips?
