< script >
var width = 400, height = 400;
var svg = d3.select("body")
.append("svg")
.attr("width", width)
.attr("height", height);
var xscale = d3.scaleLinear()
.domain([0, 10])
.range([0, width - 60]);
var x_axis = d3.axisBottom().scale(xscale).ticks(5);
var xAxisTranslate = height / 2;
svg.append("g")
.attr("transform", "translate(50, "
+ xAxisTranslate + ")")
.call(x_axis)
