Lately, there has been a fair amount of discussion about the Portuguese law proposal PL 118, both on Twitter and the Blogosphere. I’ve used NodeXL (version 1.0.1.196) to retrieve connections among Twitter users who recently tweeted the #pl118 hashtag and to visualize the resulting implicit social network. The data was collected on January 26, 2012.

A connection between two users in the above network represents either a retweet (RT) or a mention (@). The nodes are scaled by betweenness centrality and were clustered using the Clauset-Newman-Moore algorithm. The network is displayed using the Group-in-a-Box meta-layout and the Harel-Koren layout within each box.
