Each of these traces one question through cause and effect, and every claim on every one of them points back to an article you can go and read. Plenty of those articles turn up with no picture at all: a paywall, an aggregator stub, a PDF. Rather than dress one outlet's story in another outlet's photograph, each map gets a drawing of its own subject, in the site's own palette, with a line running from cause to effect.

Where the line is drawn. The drawings here are ours, and every page that shows one says so: "Illustration · thematicPro", next to the outlet's own name. An article's photograph, when it has one, always wins, and the structured data we publish about an article never claims our art as its image.
