d3.js - Slowing down link animation in D3 force layout -


in force layout, i'd slow down animation when 2 distant nodes linked.

for example: if have 2 nodes 400px apart , link established between them (after inital tick has cooled down), i'd link start @ 400px , animate down towards 100 (or standard link distance set).

you can set linkstrength lower value make linking less abrupt. so:

force.linkstrength(0.1);

linkstrength value between 0 , 1. https://github.com/mbostock/d3/wiki/force-layout#linkstrength
