How to do Radial FlexTree

[cvharris]

There are examples of radial d3 trees using the size property but I want to use flexTree to set the node size dynamically. Is there a way to create a radial tree layout with d3-flexTree?

since only the radius will vary for circles, you can consider as squares of different sizes.
you can try calculating the center

cx = x + size /2, cy = y + size/2

where size [100, 100]
