Vis.js:你能在悬停时显示属性吗？

var container = document.getElementById('network');
var data = {
  nodes: nodes,
  edges: edges
};
var options = {
  // 配置选项
};
var network = new vis.Network(container, data, options);

var nodes = new vis.DataSet([
  { id: 1, label: 'Node 1', title: 'Node 1 description' },
  { id: 2, label: 'Node 2', title: 'Node 2 description' },
  // 其他节点数据
]);

var edges = new vis.DataSet([
  { from: 1, to: 2, title: 'Edge description' },
  // 其他边数据
]);

var options = {
  interaction: {
    hover: true
  },
  nodes: {
    shape: 'circle',
    size: 20,
    font: {
      size: 14
    }
  },
  edges: {
    width: 2
  }
};

<div id="network"></div>
