This graph is about daily domain changes. Maybe if you looked here, it would help (the four values in the four tab headings): http://www.dailychanges.com/domaincontrol.com/

I'm experimenting and leaning new ways to visualize the data. I think there are better ways of doing it than a bar graphs or line plots. Well, it seems it did not work that well. GitHub uses similar visualization technique, though. Maybe next time I get it right. Here is my inspiration:

EDIT: Initially I wanted to do Sankey diagram but that came out way too complicated and there wasn't a good way to show new and deleted domains.
