韦恩图的问题，其实在于如何表示数据，韦恩图的几个关系 交、并、包含、互斥之类的，如何表达在数据中，如何自动布局都需要考虑清楚才能做，两两之间的关系、甚至多个个节点之间的关系也比较麻烦。

一个本质的问题是你绘制韦恩图的目的是为了自动布局，还是位置事先已经有了，仅仅来表达两者之间的关系，如果相交的话颜色是否要变换。

自动布局、宽度适配、相交变换、label信息、交互都需要。

如果这样的话，数据模型本身就要比较复杂，节点和关系需要两份数据

var nodes = [{name: 'a', value: xxx},{name:'b',value:xxx}];

var relations = [{relation: 'a-b',type: 'union'},{relation: 'b-c',type: 'union'}.....];

var layout = new Layout.Wayne({nodes: nodes,relations: realtions});

view.point().position('x*y').color('xxx').size('value').shape('vayne');

结论：暂时不在g2上专门实现韦恩图
