[Solved]-d3.js Animation Follow Circles on Mouse Move-d3.js

You want a mouse-over to behave like a drag?

node.on("mousemove", function(d){
    d3.event.stopPropagation(); // stop the default event handling
    d.fixed = true; // fix the moused over node
    var coords = d3.mouse(this.parentNode); // get mouse position
    d.px = coords[0]; d.py = coords[1]; // set position
    force.resume(); // resume layout
});
