我正在研究这个例子：
http://bl.ocks.org/mbostock/7607535
我把它包装成一个指令。由于某种原因，补间方法不会被触发。
var transition = d3.transition()
.duration(d3.event.altKey ? 7500 : 750)
.tween("zoom", function(d) {
var i = d3.interpolateZoom(view, [focus.x, focus.y, focus.r * 2 + margin]);
return function(t) { zoomTo(i(t)); };
});
补间与角度不兼容吗？知道我应该从哪里开始寻找？

我从上面http://bl.ocks.org/mbostock/7607535做了一个小小提琴。
我已经通过指令合并了d3 svg组件，并且补间效果非常好。

问题的根源是datejs。删除后，D3转换工作正常。
