--自定义图表的第二次 fiddle --随机地将气泡放置在靠近区域的区域，但不能考虑到与中心图表区域重叠或脱落的情况。 http://jsfiddle.net/NYEaX/1484/
我想结合 donut 饼和气泡图来产生这样的精确结果
我最接近的 - 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');
/* ------- ANIMATE BUBBLES -------*/
我还考虑过尝试对气泡图进行聚类，以至少始终将颜色分组在一起 - 但这仍然与所需的图表不匹配 - 需要颜色气泡接近匹配的饼图段。
--这是一个聚集的变体，但橙色气泡可能夹在中间，一旦我尝试将其与馅饼合并--将不会对应。我考虑过尝试添加电荷/重力来尝试排斥气泡。
