import * as joint from '@joint/core'

    // 1.  创建画板
    var graph = new joint.dia.Graph({}, { cellNamespace: namespace })

    var paper = new joint.dia.Paper({

    // 创建矩形
    var rect = new joint.shapes.standard.Rectangle()
    rect.position(100, 30)
    rect.resize(100, 40)
    rect.attr({

    rect.addTo(graph)

    // 创建矩形-2
    var rect2 = rect.clone()
    rect2.translate(300, 0)
    rect2.attr('label/text', 'World!')
    rect2.addTo(graph)

    // 创建连接线
