I'm sorry, how is this supposed to work as an infographic? Multiple timelines -- but they're not aligned next to one another, so there's no way to compare them.

I'm sorry, how is this supposed to work as an infographic? Multiple timelines -- but they're not aligned next to one another, so there's no way to compare them.
