Synopsis: William Playfair invented graphs when he needed a way to illustrate the data in one of his books.
I was immediately intrigued when I saw Line, Bars and Circles. It had never occurred to me that graphs haven’t always been used! The subtitle, however, describes the book: How William Playfair Invented Graphs. What an interesting story.
After his father’s death, William Playfair, a 12-year-old dreamer and practical jokester, went to live with his older brother, a scientist. It was inevitable that their personalities would clash; William had to become more practical. He became an inventor, but was not practical enough to make a living. However, when he wrote a book, and needed a way to show some information, he drew a picture showing the relationship of the numbers to each other. Voila! The first line graph was made.
This is a wonderful resource to accompany a study of statistics and graphing. I really enjoyed the story behind the ubiquitous graphs we have today.
I received a free ecopy of this book from NetGalley in exchange for an honest review.
