1. Potential unintended areas of impact

   • None

2. What I did to test those areas of impact (or what existing automated tests I relied on)

   • N/A

3. What automated tests I added (or what prevented me from doing so)

   • Animation speed is not worth testing.

LGTM 👍

Have you played with 500 millis? Anything that moves draws attention, in this case the graph.

Have you played with 500 millis? Anything that moves draws attention, in this case the graph.

Yes, I tried 500 millis, but it seemed too slow to me. Chris mentioned that this animation may worsen the experience of comparing. I didn't want to remove it entirely but rather to increase speed. I think that with 250 millis, the speed matches that of animation seen on the web stats.

Thank you for your quick review!
