Help to understand how precomputed the layout

Hi @anvaka,

Thanks for building it, I'm trying to understand how it works and I don't understand.

I'm building a big graph (some transaction Bitcoin) and I have to need to precompute the layout with this module but I don't understand how to work.

I have saved my graph inside the simple file and it has this form:

**TO_NODE**|INFORMATION_LINK|INFORMATION_LINK|INFORMATION_LINK|**FROM_NODE**

I want to build a wrapper of your module for creating the configuration to a string pattern, but I have need to help what is the corruptive value for the file `labels.json` for work the module

If I understand the labels.json with my example have this form:

`['TO_NODE', 'FROM_NODE']`

if I understand how I can insert the information for the link? if I don't undestend can you help me?

The issue asks how labels.json should represent TO_NODE, FROM_NODE, and link information, but names no source entry point or test. Start by locating labels.json and the code that reads it; done would be a clear explanation or documentation of the accepted file format and how link information is represented.
