html>添加节点以及添加连线的方法
- 简单的添加两个节点，以及一条连线（除此之外 nodes 和 edges 还支持
update和remove操作）
network.body.data.nodes.add([{id: "addNode01",label: "add01",level: 5},{id: "addNode02",label: "add02",level: 5}]);
network.body.data.edges.add([{id: "addEdge01",from: "addNode01",to: "addNode02"}]);
2. 比较复杂的在线编辑，在 option 中启用 manipulation 配置：addNode、editNode、deleteNode、addEdge、editEdge 和 deleteEdge。
var options = {
autoResize: true, // Default：true 如果为true，则网络将自动检测其容器何时调整大小，并相应地重新绘制自己。如果为false，则可以在使用函数redraw（）和setSize（）调整容器的容器大小后强制重新绘制网络。
clickToUse: false, // Default：false 将网络配置clickToUse为时，只有在激活时才会对鼠标和触摸事件做出反应。激活时，网络周围会显示蓝色阴影边框。通过点击该网络将网络设置为活动状态，然后通过点击网络外部或按ESC键将其更改为非活动状态。
width: "100%", // 画布的宽度。可以百分比或像素
height: "100%",
locale: "cn", // 选择区域设置。默认情况下，该语言是英语。
locales: locales, // 语言环境 默认情况下 'en'， 'de'， 'es'， 'it'， 'nl' 'pt-br'， 'ru' 的支持。
configure: {
enabled: false, // 打开或关闭配置界面。
filter: function(option, path){
return path.indexOf('physics') !== -1
}, // 如果布尔值为true，则给出所有选项，false将不显示任何值。 如果提供了字符串，则允许以下任意组合：节点，边，布局，交互，操纵，物理，选择，渲染器。随意想出一个有趣的分开的字符。最后，当提供一个字符串数组时，任何前面提到的字段都被接受。当提供一个函数时，你会收到两个参数。选项对象中的选项和选项的路径。如果它返回true，则选项将显示在配置程序中。
// container: undefined,
showButton: true // 在配置器底部显示生成选项按钮。
},
