因为数据要展示双向关系，最终选用了cytoscape.js。
效果如图，echarts只能显示单项数据关系。
据我理解，这个插件分两种，一种是基于jquery的，另一种是原声的。
基于jquery是加在jquery对象上的。因为基于jquery的无法在线上显示关系。最终选择了原生

var layout = cy.layout({
name: 'concentric',这是控制图形形状的
fit:true,
padding: 30, // the padding on fit
startAngle:4/ 2 * Math.PI, // where nodes start in radians
sweep: undefined, // how many radians should be between the first and last node (defaults to full circle)
clockwise: true, // whether the layout should go clockwise (true) or counterclockwise/anticlockwise (false)
equidistant: false, // whether levels have an equal radial distance betwen them, may cause bounding box overflow
minNodeSpacing: 100 // min spacing between outside of nodes (used for radius adjustment)
});
layout.run();
这就是简单的初始化及一些配置。
