        }],
        label: {
            // fontWeight: 'bold',
            rotate: 50
        },
        top: '18%',
        bottom: '14%',
        layout: 'radial',
        symbol: 'circle',
        expandAndCollapse: false,
        symbolSize: 30,
        lineStyle: {
            curveness: 0,
        },
    }]
};

What is expected?

根节点只有一个二级子节点，二级子节点有多个三级子节点，根节点的lable和二级节点的lable在节点全部展开的情况下不会重叠
