Worth a thousand words

Three charts that are worth a thousand words

A good graphic can tell a story, bring a lump to the throat, even change policies. Here are three of history's best.

The chart above used statistics from William Farr and Florence Nightingale.

Nightingale compared his numbers with her own on the deaths of soldiers to great effect. By showing that even in peacetime a soldier faced twice the risk of dying in a given year as a civilian, she campaigned successfully for better conditions in barracks. The pair were instrumental in setting up a royal commission of inquiry into sanitary conditions during the Crimean war.
