Basically, the system downloads hoards of data off of our server and displays it in a chart format on the browser. It supports drill-downs, meaning that you can narrow down and display charts more specific to what you're looking for. I'll show an example below.
Clicking OS would make another chart appear on the right, with specific information about the OS. I could continue to drill-down and make more and more charts appear. Once there are already 3 charts displaying, an arrow bar will appear on the left to view older charts if you continue to drill down.
