I have a dataset in format
.txt of a directed network, containing a matrix
A of dimension
m x 2, where each row gives the labels of two nodes showing a direct link.
For example, when the network has $4$ nodes, the matrix
A could be
A = [1 2; 1 3; 2 1; 2 4; 3 2; 4 1; 4 2]
where the first row means that there is a link from
2, the second row means that there is a link from
Could you suggest me a way to draw the network specified by
A in Mathematica?
