Reshape graph layout

I am trying to render doubleTree(https://gojs.net/latest/samples/doubleTree.html) & my nodes are directed in linear manner only :
for example :


"[{"key":0,"n":"Nikhil","__gohashid":438},{"key":1,"n":"Shital","parent":0,"dir":"left","__gohashid":439},{"key":2,"n":"Chandmalji","parent":1,"dir":"left","__gohashid":440},{"key":3,"n":"Mulibai  ","parent":2,"dir":"left","__gohashid":441},{"key":4,"n":"Hiralalji","parent":3,"dir":"left","__gohashid":442},{"key":5,"n":"Bhojrajji","parent":4,"dir":"right","__gohashid":443},{"key":6,"n":"Rajkumar","parent":5,"dir":"right","__gohashid":444},{"key":7,"n":"Rahul","parent":6,"dir":"right","__gohashid":445},{"key":8,"n":"Manisha","parent":7,"dir":"right","__gohashid":446},{"key":9,"n":"Parasmal","parent":8,"dir":"left","__gohashid":447},{"key":10,"n":"Preeti","parent":9,"dir":"right","__gohashid":448},{"key":11,"n":"Abhay ","parent":10,"dir":"right","__gohashid":449},{"key":12,"n":"Varun ","parent":11,"dir":"right","__gohashid":450}]"

I want to show this straight line graph in circular manner.
Is that possible?

Any clue or help will be greatly appreciated.

Use CircularLayout?
