私のx軸には現在、番号付きの目盛りがあります。目盛りをオブジェクトのデータ (具体的にはキーワード値)に置き換えたい。どうすればこれを達成できますか?
var dataset = [
{"keyword": "payday loans", "global": 1400000, "local": 673000, "cpc": "14.11"},

];
var xAxis = d3.svg.axis()
.scale(xScale)
.orient("bottom");
// xAxis
svg.append("g") // Add the X Axis
.attr("class", "x axis")
.attr("transform", "translate(0," + (h) + ")")
.call(xAxis);
//xAxis Label
svg.append("text")
.attr("transform", "translate(" + (w / 2) + " ," + (h + margin.bottom - 5) +")")
.style("text-anchor", "middle")
.text("Keyword");
