Network Analysis using R
Try this R code:

library(igraph)
dfr &lt;- data.frame(idMovie1=c(2,1,4), idMovie2=c(3, 2, 3), strength=c(23,80,10))

igr &lt;- igraph::graph.data.frame(dfr)
plot(x = igr,
     edge.curved=FALSE, edge.width=log(edge_attr(igr)$strength), edge.label=edge_attr(igr)$strength,
     main="Graph of Movie Strengths")


Works only for small daasets. visualizations get ugly quickly.
