As a stretch goal, once you have a bunch of super-long-ago data, it would be sweet to be able to graph the data not just linearly in time, but also along various warped scales so that instead of equal intervals representing equal years, equal intervals represent:
It would be nice to have more datasets that try to go way back before 1800 -- like those used by this OpenPhil report, or books like “Why The West Rules”, “Secular Cycles”, etc. Here is a link to a pdf will all the figures in “Why The West Rules”, albeit they are mostly maps.

An equal number of human lives (as Holden does here to my delight)
An equal amount of economic growth
