My "commits per quarter" graph jumps from Q4 2015 to Q1 2017, without showing any data for the quarters of 2016. That's interesting because I moved from the US to the UK, which was quite a shock! It took me a while to really feel comfortable in my new home, especially since I had just taken a new job and it too was changing a lot. I guess I really didn't really "fit in" at the new job. Upon reflection, I guess 2016 was a bit of a lost year for me.
I'm impressed. This visualization is _really_ advanced.
Or maybe the labels are just incorrect.
