This is a really good presentation. Very informative. I want to get a copy of the slides for my own studies. Subscribed. Thanks

such an inspiring team!

What's your opinion on using something like an exponential axis in the case where you have data over a wide range, but you also want to see subtleties in the variances of data? I am of course assuming that this would be clearly labeled and also you would have horizontal lines to show what's happening you have him clustered closer together at one end of the graph and farther apart at the other end. I once did something like this when I was doing a presentation on the history of the Levant going back about four million years BCE to present day. On the bottom of all my slides I had to running timeline to show where in history we were, but I use exponential scaling so that the first 4,000,000 years wouldn't take up the entire timeline, leaving everything else scrunched near the beginning. My thought was that the closer you got to the present day, the more they were notable events happening in rapid succession (in the early part of the graph there were huge amounts of times between social and technological changes), and also that it mirrored human perception in the way that we think about remembering the past or looking back at the past.
