My result is based on database dynamic query JSON file, there are more than 1000, on the interface shows very much, now want to more than 10, the rest is expressed in a node, and put the special nodes behind the JSON,
D3. Layout. Tree (). The size (height, halfWidth]), children (function (d) {return d.w inners. }),

The children (function (d) {return d.w inners. }), how to deal with here can only pick up before 10?
