D3js可摺疊樹減少節點之間的長度

Question

我在可摺疊樹中顯示json。樹顯示正常，但節點之間的長度應減少。請讓我知道如何在d3js中做到這一點。

var treeData = { 
     "name": "test", 
     "description": "sdfdsfdf", 
     "children": [ 
     { 
      "name": "test", 
      "description": "test", 
      "children": [ 
      { 
       "name": "test", 
       "description": "dfdsfdsfdf" 
      }, 
      { 
       "name": "truetest", 
       "description": "status check", 
       "children": [ 
       { 
        "name": "variable test", 
        "description": "variable test" 
       }, 
       { 
        "name": "variable test", 
        "description": "variable test" 
       } 
       ] 
      }, 
      { 
       "name": "uuuu", 
       "description": "trest", 
       "destination": "10.154.130.1" 
      } 
      ] 
     } 
     ] 
    } 
     var totalNodes = 0; 
     var maxLabelLength = 0; 
     // variables for drag/drop 
     var selectedNode = null; 
     var draggingNode = null; 
     // panning variables 
     var panSpeed = 200; 
     var panBoundary = 20; // Within 20px from edges will pan when dragging. 
     // Misc. variables 
     var i = 0; 
     var duration = 750; 
     var root;
