使用python igraph绘制社区 [英] Plotting communities with python igraph

问题描述

我在python-igraph中有一个图 g 。我可以获得具有以下内容的 VertexCluster 社区结构：

I have a graph g in python-igraph. I can get a VertexCluster community structure with the following:

community = g.community_multilevel()

community.membership 给我列出了图中所有顶点的组成员身份的列表。

community.membership gives me a list of the group membership of all the vertices in the graph.

我的问题确实很简单，但是我还没有找到关于python的特定答案。如何绘制具有社区结构可视化的图形？最好是PDF格式，例如

My question is really simple but I haven't found a python-specific answer on SO. How can I plot the graph with visualization of its community structure? Preferably to PDF, so something like

layout = g.layout("kk")
plot(g, "graph.pdf", layout=layout) # Community detection?

非常感谢。

推荐答案

您可以将VertexClustering对象直接传递给plot函数；它将自动绘制基础图形，并自动为群集选择颜色。可以照常在layout = ...关键字参数中指定所需的布局。

You can pass your VertexClustering object directly to the plot function; it will automatically plot the underlying graph instead and select colors automatically for the clusters. The desired layout can be specified in the layout=... keyword argument as usual.
