Example of a scatterplot created with Processing. You'll need to create a 'data' folder inside the sketch folder and save twitter.csv inside it. Data: Top 100 Twitter users according to number of followers (in 2010?). Based on https://docs.google.com/spreadsheet/ccc?key=0AonYZs4MzlZbdFRwUEJxd1pQYTF0N0VqSENoY1Z6dWc#gid=0.
