这称为邻接矩阵。

R FAQ 中有一些信息关于绘制表示为矩阵的社交网络:

Plotting social network data can be easily done with the igraph package in R. [...] In order for the igraph package to recognize this table as a network, we can first convert it to a matrix. Then, if we wish to calculate graph-related statistics on it (betweenness, closeness, degree), we can use the matrix to create a graph object.

FAQ 给出了一些示例，生成了社交图，例如:

igraph 库本身是 documented here - 它可以生成更复杂的示例 - 请参阅 screenshots page和下面的例子:
