## 第一步：安装npm包 ##

npm install mxgraph

## 第二步：在mxgraph.vue中使用mxgraph ##

<template>
      <div>
        <div ref="graphContainer">
        </div>
      </div>
    </template>
    
    <script>
    import mx from 'mxgraph'
    
    export default { 
      name: 'Application',
      data() { 
        return { 
        }
      },
      mounted() { 
        const mxgraph = mx({ 
          mxImageBasePath: './src/images',
          mxBasePath: './src'
        })
        const MxGraph = mxgraph.mxGraph
        var graph = new MxGraph(this.$refs.graphContainer)
    
        // Gets the default parent for inserting new cells. This
        // is normally the first child of the root (ie. layer 0).
        var parent = graph.getDefaultParent()
    
        // Adds cells to the model in a single step
        graph.getModel().beginUpdate()
        try { 
          const v1 = graph.insertVertex(parent, null, 'Hello,', 20, 20, 80, 30)
          const v2 = graph.insertVertex(parent, null, 'World!', 200, 150, 80, 30)
    
          graph.insertEdge(parent, null, '', v1, v2)
        } finally { 
          // Updates the display
          graph.getModel().endUpdate()
        }
      }
    }
    </script>
