Lines, Bars and Circles: How William Playfair Invented Graphs

(3) K-3 Illustrated by Marie-Ève Tremblay. This short-form biography describes inventor and "jack-of-all-trades" William Playfair's road to creating the line graph, bar graph, and pie chart, appreciated only after his death. Like Playfair, illustrator Tremblay thinks outside the box: e.g., a giant-size Playfair stepping out from a building's roof accompanies "Meikle's workshop felt too small to hold all Will's grand dreams." Nuts-and-bolts sidebars and back matter supplement the peppy narrative.
