如何在D3旭日形图中正确旋转文本标签

Question

In the following D3 sunburst :

http://jsfiddle.net/maxl/eabFC/

.attr("transform", function(d) {
    return "rotate(" + (d.x + d.dx / 2 - Math.PI / 2) / Math.PI * 180 + ")";
});

The labels in the left quadrants are upside down, I would like to perform a rotation on them so that the text reads from left to right.

The transformation should only apply to the arcs from approximately 100 degree to 270 degree.

I've edited your jsfiddle here: http://tributary.io/inlet/4127332/

You are going to have to deal with your long labels and the above example shows how to do multi-line.

Also note that you are using an old version of d3, it is no longer necessary to call d3.layout separately. Here is the link to new shiny version of d3:
