[Solved]-d3js zoom + drag causes conflict-d3.js

I have implemented individual dragging of nodes working along with overall zooming and panning functionality. Used stopPropagation of the event in dragstart event of circles.

Hope this helps.

var move = d3.behavior.drag()
    .on("dragstart", function() {
        d3.event.sourceEvent.stopPropagation();
    });

Working JSFiddle
