D3 vertical line graph - d3.js

Question

I have a line (& area) graph which works ok, when horizontal. But I really need it to be vertical, to stand up. I have tried all kinds of changes to the existing code. Mostly with some strange results.
Here’s the code (modified it a bit). Is there a way to change it to make the graph vertical?:
var x = d3.scale.linear().domain([1, itemCount]).range([0, width]);
var y = d3.scale.linear().domain([0, maxValue]).rangeRound([height, 0]);
// Set up linar x and y axis.
var xAxis = d3.svg.axis().scale(x).ticks(10);
var yAxis = d3.svg.axis().scale(y).ticks(2).orient("left");
// Line graph.
line = d3.svg.line()
.interpolate("basis")
.x(function (d) {
return x(d.x);
})
.y(function (d) {
return y(d.y);
});
// Create SVG element.
var svg = d3.select("body")
.append("svg")
.attr("width", width)
.attr("height", height);
// X-Axis, to bottom.
svg.append("svg:g")
.attr("class", "axis")
.attr("transform", "translate(1," + height + ")")
.call(xAxis);
//Y-Axis
svg.append("svg:g")
.attr("class", "axis")
.attr("transform", "translate(40, 1)")
.call(yAxis);
// Horizontal axis guide lines.
svg.selectAll("line.y")
.data(y.ticks(5))
.enter()
.append("line")
.attr("x1", 0)
.attr("x2", width)
.attr("y1", y)
.attr("y2", y)
.style("stroke", "#000000")
.style("stroke-opacity", 0.1);
// Vertical axis guide lines.
svg.selectAll("line.x")
.data(y.ticks(5))
.enter()
.append("line")
.attr("x1", x)
.attr("x2", x)
.attr("y1", 0)
.attr("y2", this.heightInside - pushDown)
.style("stroke", "#000000")
.style("stroke-opacity", 0.1);
// Set up domains. Nice ensures the domains ends on nice round values.
x.domain([dataValues[0].x, dataValues[dataValues.length - 1].x]).nice();
y.domain([d3.min(dataValues, function (d) { return (d.y); }),
d3.max(dataValues, function (d) { return (d.y); })])
.nice();
// Draw line on graph.
svg.append("svg:path")
.attr("class", "line")
.attr("d", line(dataValues))
.style("stroke", function(d) { return colors[i]; });
// Marks.
svg.selectAll("circle_" + i)
.data(dataValues)
.enter()
.append("circle")
.style("fill", function(d) { return _this.colors[i]; })
.attr("r", 4)
.attr('cx', function (d) { return x(d.x); })
.attr('cy', function (d) { return y(d.y); });
