想象一下，您有一个像这样的数据集:

Imagine you have a dataset like this:

data = [{
  posx: 100,
  posy: 100,
  img: "https://cdn0.iconfinder.com/data/icons/flat-round-system/512/android-128.png",

}, {
  posx: 200,
  posy: 200,

  img: "https://cdn1.iconfinder.com/data/icons/social-media-set/24/Reverbnation-128.png"
}, {
  posx: 300,
  posy: 300,

  img: "https://cdn1.iconfinder.com/data/icons/user-pictures/100/male3-128.png"
}]

在svg中使像这样的defs:

Make defs like this in svg like this:

var defs = svg.append('svg:defs');

遍历所有数据，并使用图像和圆进行尽可能多的定义. 在圆内填充像这样.style("fill", "url(#grump_avatar" + i + ")");

Iterate over all the data and make as many defs with image and circle. Inside circles's fill pass the def's id like this .style("fill", "url(#grump_avatar" + i + ")");

data.forEach(function(d, i) {
  defs.append("svg:pattern")
    .attr("id", "grump_avatar" + i)
    .attr("width", config.avatar_size) 
    .attr("height", config.avatar_size)
    .attr("patternUnits", "userSpaceOnUse")
    .append("svg:image")
    .attr("xlink:href", d.img)
    .attr("width", config.avatar_size)
    .attr("height", config.avatar_size)
    .attr("x", 0)
    .attr("y", 0);

  var circle = svg.append("circle")
    .attr("transform", "translate(" + d.posx + "," + d.posy + ")")
    .attr("cx", config.avatar_size / 2)
    .attr("cy", config.avatar_size / 2)
    .attr("r", config.avatar_size / 2)
    .style("fill", "#fff")
    .style("fill", "url(#grump_avatar" + i + ")");

})
