Node size increasing on double click on node D3 v4

[iamdeepakbasnal]

How to prevent increasing node size on double click on node. I disabled the double click zoom behaviour but node size still increasing. Here is my code for disable zoom behaviour on double click

svg.call(d3.zoom().scaleExtent([0.3, 2]).on("zoom", function() {



    newTag.attr("transform", d3.event.transform)

})).on("dblclick.zoom", null)

Also I tried to prevent from double click event on node.

var svg = d3.select("svg"),

    width = +svg.attr("width"),

    height = +svg.attr("height");




var newTag = svg.append("g");




var node = newTag.attr("class","nodes")

      .selectAll("circle")

      .data(graph.nodes).enter()

      .append("g").attr("class", "entity")

      .on("click", clicked)

      .on("dblclick", null)

      .call(d3.drag().on("start", dragstarted).on("drag",

       dragged).on("end", dragended));

How can i prevent increasing node size on node double click.
