之前有用过d3js实现拓扑结构，这次需要调取一些kubernetes后台数据，发现angularjs已经能够注入d3来做这件事了，很开心啊
首先注入d3js
(function () {
'use strict';
angular.module('Myapp', []).directive("d3MinionBarGauge", ["d3DashboardService", function(e) {
return {
restrict: "E",
scope: {
data: "=",
thickness: "@",
graphWidth: "@",
graphHeight: "@"
},
link: function(t, a, n) {
var r = function(e) {
function n(e, a) {
return null === a || void 0 === a ? t.render(e) : s(a, e)
}
function r(e) {
var t = e.data
, a = c(t);
o(a, e.width, e.height)
}
function o(t, n, r) {
v = e.select(a[0]).append("svg").attr("width", "100%"),
b = e.select(a[0]).append("svg").attr("width", "100%");
var o = v.attr("class", "chart").attr("width", n).attr("height", r - 25).append("svg:g").attr("class", "concentricchart").attr("transform", "translate(" + n / 2 + "," + r / 4 + ")");
b.attr("class", "legend").attr("width", n);
y = Math.min(n, r) / 2;
var s = (b.append("text").attr("class", "hostName").attr("transform", "translate(" + (n - 120) / 2 + ",15)"),
b.append("svg:g").attr("class", "label_legend_area").attr("transform", "translate(" + (n - 215) / 2 + ",35)"));
s.append("svg:g").attr("class", "legend_group"),
s.append("svg:g").attr("class", "label_group").attr("transform", "translate(25,11)"),

o.append("svg:g").attr("class", "path_group").attr("transform", "translate(0," + r / 4 + ")"),
o.append("svg:g").attr("class", "value_group").attr("transform", "translate(" + -(.205 * n) + "," + -(.1 * r) + ")");
l(o, t)
}
function s(e, t) {
