使 d3.js可视化布局具有响应性的最佳方法是什么?

假设我有一个直方图脚本,用于构建960 500 svg图形。我如何使这个响应,所以调整图形宽度和高度的大小是动态的?
<script>
var n = 10000, // number of trials
m = 10, // number of random variables
data = [];
// Generate an Irwin-Hall distribution.
for (var i = 0; i < n; i++) {
for (var s = 0, j = 0; j < m; j++) {
s += Math.random();
}
data.push(s);
}
var histogram = d3.layout.histogram()
(data);
var width = 960,
height = 500;
var x = d3.scale.ordinal()
.domain(histogram.map(function(d) { return d.x; }))
.rangeRoundBands([0, width]);
var y = d3.scale.linear()
.domain([0, d3.max(histogram.map(function(d) { return d.y; }))])
.range([0, height]);
var svg = d3.select("body").append("svg")
.attr("width", width)
.attr("height", height);
svg.selectAll("rect")
.data(histogram)
.enter().append("rect")
.attr("width", x.rangeBand())
.attr("x", function(d) { return x(d.x); })
.attr("y", function(d) { return height - y(d.y); })
.attr("height", function(d) { return y(d.y); });
svg.append("line")
.attr("x1", 0)
.attr("x2", width)
.attr("y1", height)
.attr("y2", height);
</script>
