目前实现效果如图，或许有更精准的半径计算方法？ |

按照xile的意见改的，可能我的实现对于这个配置项没什么效果

emptySetKey 应该用在这里吧；
key 默认可以给个 others，但是options 里如果配置了 emptySetKey，应该返回 emptySetKey

💡 问题的背景&解决方案
📝 Changelog
Venn 图处理增强：
更新了 transform 函数，使其能够处理 sets 字段为空的情况，通过返回具有计算半径和中心的默认圆形来确保空集在 Venn 图中能正确表示
修改了 computeTextCenters 函数，使其能处理包含空集的区域，为这些区域分配默认中心点 (0, 0)
实用函数改进：
增强了 intersectionArea 函数，使其能处理输入 circles 数组为空的情况，通过在 stats 对象中设置默认值并返回面积为 0
测试覆盖：
添加了新的测试用例"具有空集的 3 元素 Venn 图的数据转换"，以验证 Venn 图转换中空集的正确处理
元数据更新：
添加了变更文件，记录了 @visactor/vlayouts 和 @visactor/vutils 版本 1.0.5 的发布
☑️ 自测
🚀 Summary
更新transform算法，使得sets为空时返回一个表示含有剩余值的底层大圆。同时，在label.ts和circle-intersection.ts 中增加对边界状况的处理
