我有一个小问题就在这里：如何实现这一泡沫是唯一可点击，如果完全地放大d3js
我用这个例子（http://bl.ocks.org/mbostock/7607535）工作，我修改这样的 flare.json文件：
{
"name": "flare",
"children": [
{
"name": "Kommunikation und Umwelt",
"children": [
{
"name": "Courses",
"children": [
{
"name": "AO-Psy.",
"children": [
{"name": "Prof. A", "size": 5731,"url":"index.html"},
{"name": "Prof. B", "size": 5731},
{"name": "Prof. C", "size": 5731}
]
},
{
"name": "E&E",
"children": [
{"name": "Prof. D", "size": 5731},
{"name": "Prof. E", "size": 5731},
{"name": "Prof. F", "size": 5731},
{"name": "Prof. G", "size": 5731},
{"name": "Prof. H", "size": 5731}
]
},
{
"name": "IBSS",
"children": [
{"name": "Prof. I", "size": 5731},
{"name": "Prof. J", "size": 5731},
{"name": "Prof. K", "size": 5731}
]
},
{"name": "", "size": 0},
{
"name": "E-Gov",
"children": [
{"name": "Prof. L", "size": 5731},
{"name": "Prof. M", "size": 5731},
{"name": "Prof. N", "size": 5731}
]
},
{
"name": "Muki",
"children": [
{"name": "Prof. O", "size": 5731},
{"name": "Prof. P", "size": 5731},
{"name": "Prof. Q", "size": 5731},
{"name": "Prof. V", "size": 5731}
]
},
{"name": "Schedule", "size": 5731},
{"name": "News", "size": 5731},
{"name": "Events", "size": 5731},
{"name": "Search", "size": 5731},
{"name": "", "size": 0}
]
},
{"name": "", "size": 0}
]
},
如果我点击Prof.A，我会得到我的下一个html页面。 我的问题是，即使我没有放大这个泡泡，我也可以点击Prof.A。我只想在点击它时点击它，并且标签是可读的。
我试图“修复”缩放功能，但似乎没有任何工作。

我不能取得任何进展似乎没有任何工作，请帮助我！
