Politics/religion:
-
“ORBIS: The Stanford Geospatial Network Model of the Roman World” (very impressive historically-accurate in-browser simulation of the logistics of the ancient Roman Empire. My only regret is that I can’t think of any situation in which I actually need an exact calculation of how much it would have cost to get from Londinium to Rome during winter while avoiding the Atlantic. But some of the graphs showing cost-distances between Rome and the provinces are pretty interesting, as are some of the disparities)

-
“How Not to Be Misled by the Jobs Report” (Depicts the sampling error associated with each estimate by providing an animation showing repeated draws assuming the point-estimate is the ground truth. Good for showing you how easily ‘patterns’ show up with a few data points.)
