Every economics student knows that graphs are a big part of how economists tell "their stories." Indeed, a picture can be worth a 1000 words. Arguably the bible of modern economics, Adam Smith's Wealth of Nations did not contain a single graph or chart. Who is credited with introducing the use of charts to convey economic information?Congratulations to David Graham for correctly identifying William Playfair as the first economist to incorporate charts in his writings in order to convey difficult to understand concepts. Playfair is credited with inventing the line, bar, and pie charts.
