Graphic created using Gephi and Adobe Illustrator. The network graph shows eight potential communities that emerge from a sample of 50,000 tweets scraped just one hour after the Westminster attack on March 22, 2017. Each color on the graphic represents a different community of tweets relating to the attack. A node can connect to two different colors, but is colored based on its original source tweet. The lines represents retweets of original tweets sent by one account. Blog post explaining the analysis can be found here.
Here is a photo grad of some screenshots I took during the process:
