我正在尝试为一个项目开发一个 d3js 和弦。我可以渲染图表，但我有一些问题要让它在网页中响应。简而言之，我想将我的图表绑定到一个与引导模板连接的 div 'chartContainer'。
这是一段代码：
<div class="row">
<div class="col-xs-12">
<div id="chartContainer">
<div id="tooltip"></div>
<!--<script src="https://d3js.org/d3.v3.min.js" charset="utf-8"></script>-->
<script src="js/d3.min.js" charset="utf-8"></script>
<script src="js/underscore.js"></script>
<script src="js/mapper.js"></script>
<script>
//*******************************************************************
// CREATE MATRIX AND MAP
//*******************************************************************
d3.csv('trade-a.csv', function (error, data) {
var mpr = chordMpr(data);
mpr
.addValuesToMap('seller')
.addValuesToMap('buyer')
.setFilter(function (row, a, b) {
return (row.seller === a.name && row.buyer === b.name) ||
(row.seller === b.name && row.buyer === a.name)
})
.setAccessor(function (recs, a, b) {
if (!recs[0]) return 0;
return recs[0].seller === a.name ? +recs[0].flow1 : +recs[0].flow2;
});
drawChords(mpr.getMatrix(), mpr.getMap());
});
//*******************************************************************
// DRAW THE CHORD DIAGRAM

function drawChords (matrix, mmap) {
var w = 980, h = 800, r1 = h / 2, r0 = r1 - 110;
//Qui i settaggi della scala dei colori vedere anche https://github.com/mbostock/d3/wiki/Ordinal-Scales#categorical-colors

.attr("d", arc);
g.append("svg:text")
.each(function(d) { d.angle = (d.startAngle + d.endAngle) / 2; })
.attr("dy", ".35em")
.style("font-family", "helvetica, arial, sans-serif")
.style("font-size", "9px")
.attr("text-anchor", function(d) { return d.angle > Math.PI ? "end" : null; })

//Settaggi della tooltip del gruppo

.style("left", function () { return (d3.event.pageX - 130)+"px";})
chordPaths.classed("fade", function(p) {
return p.source.index != i
&& p.target.index != i;
});
}
}
</script>
</div>
</div>
</div>
我尝试添加此代码
var canvas = d3.select("#chartContainer").append("svg:svg")
但它不起作用！有什么建议么？
