Venn diagram layout with d3.js
提问by Yaron Naveh
Is there a sample on how to do Venn diagram using d3.js? I know about the twosamples:
是否有关于如何使用 d3.js 绘制维恩图的示例？我知道这两个样本：
that are provided on D3 website. However they force me to calculate by myself the x.y position of the circles. I am hoping to feed just the data (circle sizes and overlap size) to a function/chart and it should do the layout for me.
D3网站上提供的。然而，他们强迫我自己计算圆圈的 xy 位置。我希望只将数据（圆圈大小和重叠大小）提供给函数/图表，它应该为我做布局。

To get an understanding of the required algorithm, read Leland Wilkinson's paper, Exact and Approximate Area-proportional Circular Venn and Euler Diagrams, published in IEEE TVCG February 2012. To the best of my knowledge no one has yet implemented a venneulerlayout in D3, but that would make a fantastic D3 plugin.
要了解所需的算法，请阅读 Leland Wilkinson 的论文Exact and Approximate Area-proportional Circular Venn and Euler Diagrams，发表于 IEEE TVCG 2012 年 2 月。 据我所知，目前还没有人venneuler在 D3 中实现布局，但是这将是一个很棒的D3 插件。
