Note: 2009 marks the 250th anniversary of the birth of William Playfair [1759 –1823] , Scottish engineer and political economist, the founder of graphical methods of statistics. Playfair invented four types of diagrams: the line graph and bar chart of economic data, which first appeared in his Commercial and Political Atlas, published in 1786, and the pie chart and circle graph, used to show part-whole relations.
