"It wasn't until the late 18th and early 19th centuries that most of the graphs we use today were invented, applied, or dramatically improved by Scottish social scientist named William Playfair. Playfair invented the bar graph, was the first to use line graphs to represent change through time, and, on one of his off days, invented the pie chart"
