缺少标签 - Cola.js/D3.js

Question

我正在尝试调整下面的 Cola.js 示例以使用内部 json 而不是点文件

http://marvl.infotech.monash.edu/webcola/examples/unix.html

我想将此图用作流程图。下面是我使用内部 json -

创建的 fiddle

var d3cola = cola.d3adaptor().convergenceThreshold(0.1);

var width = 960, height = 700;

var outer = d3.select("body").append("svg")
       .attr({ width: width, height: height, "pointer-events": "all" });

    outer.append('rect')
       .attr({ class: 'background', width: "100%", height: "100%" })
       .call(d3.behavior.zoom().on("zoom", function(d) {
          vis.attr("transform", "translate(" + d3.event.translate + ")" + " scale(" + d3.event.scale + ")");
       }));

var vis = outer
      .append('g')
      .attr('transform', 'translate(250,250) scale(0.3)');

     outer.append('svg:defs').append('svg:marker')
         .attr({
                id: 'end-arrow',
                viewBox: '0 -5 10 10',

图表似乎渲染得很好。但是，矩形内的标签丢失了。

有什么可能出错的建议吗？ Objective是把矩形展开，让标签能放进去？

谢谢

通过更改

使其正常工作

.text(function (d) { return d.name; })

到

.text(function (d) { return d.nodes; })

var d3cola = cola.d3adaptor().convergenceThreshold(0.1);

var width = 960, height = 700;

var outer = d3.select("body").append("svg")
       .attr({ width: width, height: height, "pointer-events": "all" });

    outer.append('rect')
       .attr({ class: 'background', width: "100%", height: "100%" })
       .call(d3.behavior.zoom().on("zoom", function(d) {
          vis.attr("transform", "translate(" + d3.event.translate + ")" + " scale(" + d3.event.scale + ")");
       }));

var vis = outer
      .append('g')
      .attr('transform', 'translate(250,250) scale(0.3)');

     outer.append('svg:defs').append('svg:marker')
         .attr({
