Explainers draw every page

Ask how a place, a past or a thing works and every page of the answer is a picture: a rough map drawn in shapes, a chart, a big number. Chris asked for a brief geography of the Mongols and got a page of text; now agents draw it.

say "The Mongols held the grass belt from Korea to Hungary."
