January 23 2010, 5:08pm
Built using Axiis (open source data visualization framework) this visualization shows the historical browser breakdown of visitors to W3schools.com. It has the ability to filter by browser type. Each of the concentric rings are essentially pie charts showing the percentage of visitors using each browser for a particular time slice, starting with January 2002 in the center and working out to August 2009.
