An anonymous reader writes "Back in November, Mozilla Labs and the Metrics Team together launched the first Mozilla Open Data Visualization Competition. While we set out to discover creative visual answers to the open question, "How do people use Firefox," we really didn't know what level of participation to expect from the Mozilla and data analysis communities. In fact, we were overwhelmed by both the number and quality of submissions – so much so that we had to give ourselves an extra few days to thoroughly review them. In all, we received 32 high-caliber submissions. The visualizations took a number of forms, from tools to easily query the data to interactive web applications. They also covered a broad range of important topics, from plugin memory consumption to user web activities."
