About the author

Born in Scotland in 1759, William Playfair was an engineer and political economist whose ideas helped shape modern data visualization. He is best remembered for introducing graphic ways to present numerical information, especially in The Commercial and Political Atlas (1786), where he used line and bar charts to show economic trends.

Later, in Statistical Breviary (1801), he published an early pie chart and is widely credited as a founder of statistical graphics. What now feels natural in business reports, newspapers, and classrooms was strikingly original in his time: he believed people could grasp patterns and comparisons faster when numbers were turned into images.

Playfair's life was far from quiet, and his career ranged across engineering, economics, writing, and public controversy. But his lasting achievement is simple and enormous: he gave the modern world some of its clearest visual tools for thinking with data.
