关系图节点能否是自定义组件echarts 折线配置项内容和展示

比如节点传入封装好的imagecard组件，而不仅仅是设置symbol

      option = {
    title: {
        text: 'Awesome Chart'
    },
    xAxis: {
        data: ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat']
    },
    yAxis: {},
    series: [{
        type: 'line',
        data:[220, 182, 191, 234, 290, 330, 310]
    }]
};
