1、点击隐藏，控制隐藏节点4以及相关的边
2、点击显示，显示节点4以及相关的边
3、点击添加颜色，给指定节点4添加颜色
demo如下：

// 第三步：设置数据

// 第四步：配置G6画布
var net = new G6.Net({
id: 'c1', // 容器ID
fitView: 'autoZoom',
mode: 'none',
width: 500, // 画布宽
height: 500 // 画布高
});
// 第五步：载入数据
net.read(Util.clone(data));
// 第六步：渲染关系图
net.render();
$('#getEdges').on('click', function(){
reRender(); // 重新渲染
var keyNode = net.find('a285b5dc');
keyNode.hide();
net.refresh();
});
$('#getLinkNodes').on('click', function(){
reRender(); // 重新渲染
var keyNode = net.find('a285b5dc');
keyNode.show();
net.refresh();
});
$('#getUnLinkNodes').on('click', function(){
reRender(); // 重新渲染
var keyNode = net.find('a285b5dc');
net.update(keyNode, {
color: '#00B07C'
});
net.refresh();
});
function reRender(){
net.clear();
net.read(Util.clone(data));
net.render();
}
