About the author

Born in Scotland in 1759, William Playfair worked as an engineer, writer, and political economist. He is remembered today as a pioneer of statistical graphics because he used visual forms to explain economic information in ways readers could understand quickly.

In The Commercial and Political Atlas (1786), he introduced line and bar charts to show trade and economic trends. Later, in Statistical Breviary (1801), he published what is widely regarded as the first pie chart. These ideas seem ordinary now, but at the time they were a striking new way to make complex numbers clear.

Playfair's life was varied and sometimes turbulent, and he wrote on politics and finance as well as statistics. He died in 1823, but his influence lasts wherever people use charts to tell a story with data.
