My design goal was that arrow intersection was at a minimum, which had to be violated today (lots of DoW's), and that there was enough information at the reader's fingertips (when DoW occured, color of alliance).
Yes I know an alternative exists
Given that very few people even see these charts (judging by comment volume), I'm not entirely sure why I'm updating this. Oh well.
So it seems I really fail at reading DoWs
