d3 js - 将气泡聚类到细分

- 自定义图表的第二小提琴 - 随机将气泡放置在靠近区域的区域，但不能解释重叠或从中央图表区域掉落。 http://jsfiddle.net/NYEaX/1484/

我想结合一个doughtnut馅饼和一个气泡图来产生一个像这样的确切结果

我最接近的是 - 就在这里。

/* ------- ANIMATE BUBBLES -------*/


// generate data with calculated layout values

var data = bubbledata(data);

var nodes = bubble.nodes(data)
  .filter(function(d) {
    return !d.children;
  }); // filter out the outer bubble


var bubbles = bubs.selectAll('circle')
  .data(nodes);



bubbles.enter()
  .insert("circle")
  .attr('transform', function(d) {
    return 'translate(' + d.x + ',' + d.y + ')';
  })
  .attr('r', function(d) {
    return d.r;
  })
  .style("fill", function(d) {
    return color(d.group);
  });


bubbles = bubbles.transition()
  .transition()
  .duration(250)
  .attr('transform', function(d) {
    return 'translate(' + d.x + ',' + d.y + ')';
  })
  .attr('r', function(d) {
    //console.log("dr", d.r)
    return d.r;
  })
  .ease('sine');

我还试图将气泡图聚类到至少总是将颜色组合在一起 - 但这仍然不符合所需的图表 - 需要将颜色气泡接近匹配的饼图段。

- 这是一个聚集的变种，但橙色气泡可能夹在中间，一旦我尝试将它与馅饼合并 - 将不相符。我曾考虑尝试添加电荷/重力以试图让气泡排斥。 https://jsfiddle.net/tk5xog0g/20/ enter image description here

最新小提琴。 http://jsfiddle.net/NYEaX/1505/

（http://jsfiddle.net/NYEaX/1506/） - 重构

 1. -- how to animate the arcs
 2. -- how to animate the bubbles
 3. -- adding back the randomise button to test with 2 dummy data sets.

这是旧的馅饼动画，效果很好

                /* ------- ANIMATE PIE SLICES -------*/
                var slice = doughpie.select(".slices").selectAll("path.slice")
                  .data(pie(data), key);

                slice.enter()
                  .insert("path")
                  .style("fill", function(d) {
                    return color(d.data.label);
                  })
                  .style("transform", function(d, i){
                    //return "translate(0, 0)";
                  })
                  .attr("class", "slice");

                slice
                  .transition().duration(1000)
                  .attrTween("d", function(d) {
                    this._current = this._current || d;
                    var interpolate = d3.interpolate(this._current, d);
                    this._current = interpolate(0);
                    return function(t) {
                      return arc(interpolate(t));
                    };
                  })

                slice.exit()
                  .remove();
                /* ------- ANIMATE PIE SLICES -------*/

//这是当前的饼形弧 - 但是当我尝试以相同的方式为饼图设置动画时 - 它会失败。

var g = svg.selectAll(".arc")
  .data(pie(data))
  .enter().append("g")
  .attr("class", "arc");

g.append("path")
  .attr("d", arc)
  .style("fill", function(d) {
    return color(d.data.label);
  });

arc
  .outerRadius(radius - 10)
  .innerRadius(0);
