Question

I have a table in the following format:

Item A | Item B | Weight
   X   |   Y    |   2
   X   |   Z    |   5
   Y   |   Z    |   3
   Y   |   W    |   2
  ...  |  ...   |  ...

I want to generate some graph where each letter(W,X,Y,Z) is a node and have a link with some width according to the weight to the Item B.

The question is what I can use to generate this graph? Can be a tool, a Java or R library or another language. The way doesn’t matter, I only need to generate the graph.

Answer 1

Borrowing the code of digEmAll I’ll do the same in qgraph:

data <- read.table(text=
"Item A,Item B,Weight
X,Y,2
X,Z,5
Y,Z,3
Y,W,2", sep=',',header=TRUE)

library(qgraph)
qgraph(data)
