object doesn't support method or property datum error while trying to view d3js treemap in webview

I am trying to implement a treemap objectextension in qlikview but keep on getting the error

object doesn't support method or property datum. Has anyone encountered this error before? if yes how may I get around with it?

The sample is code is taken from d3js.org website. In qlikview ,I am using a hirerachy load and converting the table data into a json string to pass it into the following script(not shown here).

var treemap = d3.layout.treemap()

.size([width, height])

.sticky(true)

.value(function(d) { return d.size; });

var div = d3.select("#"+_this.ExtSettings.UniqueId).append("div")

.style("position", "relative")

.style("width", (width + margin.left + margin.right) + "px")

.style("height", (height + margin.top + margin.bottom) + "px")

.style("left", margin.left + "px")

.style("top", margin.top + "px");

alert(jsontree);

// .value(function(d) { return d.size; });

//alert(data);

d3.json("flare.json", function(error, root) {

if (error) throw error;

var node = div.datum(root).selectAll(".node")

.data(treemap.nodes)

.enter().append("div")

.attr("class", "node")

.call(position)

.style("background", function(d) { return d.children ? color(d.name) : null; })

.text(function(d) { return d.children ? null : d.name; });

d3.selectAll("input").on("change", function change() {

var value = this.value === "count"

? function() { return 1; }

: function(d) { return d.size; };

node

.data(treemap.value(value).nodes)

.transition()

.duration(1500)

.call(position);

});

function position() {

this.style("left", function(d) { return d.x + "px"; })

.style("top", function(d) { return d.y + "px"; })

.style("width", function(d) { return Math.max(0, d.dx - 1) + "px"; })

.style("height", function(d) { return Math.max(0, d.dy - 1) + "px"; });

};
