Version

5.0.2

Steps to reproduce

1. 打开ECharts官网示例

https://echarts.apache.org/examples/zh/editor.html?c=map-HK

2. 将示例代码中的

myChart.setOption(option = {
...
});

改为：

myChart.setOption(option = {
    "title": {"text": "关系地图"},
    "tooltip": {"trigger": "item"},
    "geo": {"roam": true,"map": "HK"},
    "legend": {"data": ["C1","C2","C0"]},
    "series": 
    [
        {
            "name": "关系地图",
            "type": "graph",
            "layout": 'none',
            "coordinateSystem": "geo",
            "data":
            [
                {"name": "a","x": 114.14,"y": 22.28,"category": 0,"value": 80,"symbolSize": 16},
                {"name": "b","x": 114.18,"y": 22.30,"category": 0,"value": 140,"symbolSize": 30},
                {"name": "c","x": 114.18,"y": 22.25,"category": 1,"value": 70,"symbolSize": 14},
                {"name": "d","x": 114.23,"y": 22.18,"category": 2,"value": 5,"symbolSize": 6},
                {"name": "e","x": 114.25,"y": 22.35,"category": 2,"value": 55,"symbolSize": 11}
            ],
            "links":
            [
                {"source": 0,"target": 1},
                {"source": 1,"target": 2},
                {"source": 1,"target": 3},
                {"source": 1,"target": 4}
            ],
            "legendHoverLink": true,
            "label": {"position": "right"},
            "emphasis": {"focus": "adjacency"},
            "categories": [{"name": "C1"},{"name": "C2"},{"name": "C0"}],
            "lineStyle":
            {
                "color": 'source',
                "curveness": 0.3
            }
        }
      ]
    });

3. 点击【运行】按钮

What is expected?

在地图中显示关系图

What is actually happening?

没有显示效果，打开浏览器控制台报错：
