This article shows you how to use the R language ggplot2 to draw a network diagram, the content is concise and easy to understand, it can definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

The picture to be imitated today comes from the paper Core gut microbial communities are maintained by beneficial interactions and strain variability in fish. The journal is Nature microbiology.

I have previously shared two tweets that draw network diagrams using ggraph in R language.

But the network diagram in today's paper is two two circular layouts. I don't know how to implement this with ggraph package.

After thinking about it carefully, this network diagram is a combination of dots and lines, which should be easily implemented using the geom_point () and geom_segment () functions of the ggplot2 package. Because it is a circular layout, the coordinates of the scattered points are generated directly by the circular function. If you have an idea, let's make it happen.

The first is to construct the dataset

The position coordinate of the scattered point is generated by a circular function, and the center of the circle is (0) and the radius is 4, resulting in a total of 32 points.
