How to specify a weight for a link in a VivaGraphJS graph? E.g. I want get a resulting social graph where a married couple is displayed closer than somebody only loosely known.
With the springLength I can define a general distance, but nothing that is specific per link.
Here is an example how to do it: customLinkLength.html
Unfortunately there is no easy way to find best force layout arguments, which would suite all kind of graphs.
