I'm very pleased to announce that an image from my Twitter StreamGraphs tool was chosen as the cover for the current issue of ACM Crossroads - the Student Journal of the Association for Computing Machinery. There is also a small writeup inside about the image. It depicts the streamgraph for the phrase 'data visualization' and suits the issue well since it is dedicated to the Social Web. The entire issue is available online.
Thanks to Chris Harrison, the editor-in-chief, for inviting me to contribute the image and to Senior Editor Jill Duffy for sending me some copies of the issue.
